CITATION:  1988 AIR  952            1988 SCR  (3) 115  1988 SCC  (2) 115        JT 1988 (1)   514  1988 SCALE  (1)508

ACT:      Seeking ban  on release  of  Irish  butter  for  public distribution and  human consumption  on the  ground that the butter was  contaminated by nuclear fall-out after Chernobyl disaster.

HEADNOTE: %      This special  leave petition  was directed  against the judgment and  order of  the Bombay  High Court, declining to issue a writ in the nature of Mandamus and other appropriate writ, directions  or orders,  directing the  respondents  to forbear from releasing 7500 cartons (200 MT) of Irish butter imported into  India for operation Flood Programme, supplied to the  Greater Bombay  Milk Scheme  by  respondent  No.  2, National Dairy  Development Board,  on the  ground that  the butter was contaminated by nuclear fall-out.      Soon after the Chernobyl disaster, when it was realised that the  imported milk  and food products particularly from the  EEC  countries  had  the  possibility  of  radio-active contamination, the Bhabha Atomic Research Centre took up the matter with  the respective agencies and advised them to get the representative  samples for radio-active analysis before releasing them for public distribution in India.      This Court appointed a Committee of three experts, (1) Professor  M.G.K. Menon,  Member Planning  Commission  & Scientific Advisor  to  the  Prime  Minister  (2)  Dr.  P.K. Iyenger, Director  Bhabha Atomic Research Centre, Bombay and (3) G.V.K. Rao, Vice- chairman, Economic & Planning Council, Govt. Of  Karnataka, Bangalore  to give  its opinion  on the question whether  milk and  dairy products  and  other  food products   containing    man-made    radionuclides    within permissible levels  fixed by  the Atomic  Energy  Regulatory Board on  27th August,  1987, were  safe and/or harmless for human consumption.  The Committee  of Experts  examined  the question in  depth and  by its report dt. February 19, 1988, expressed its  opinion that  the consignment of the imported butter was safe and harmless for human consumption. 116      Dismissing the special leave petition, the Court, ^

    HELD: There  was no  substance in any of the objections formulated  by   the  petitioners.   In  its   most   recent recommendations,    the    International    Commission    on Radiological  Protection  observed  that  ’limits  for.  the inhalation or  ingestion of  radio-active material depend on the concentration  of those  materials  in  limiting  target organs’. The petitioners showed different permissible limits in different  countries as France, UK, E.E.C., and Australia at 3700,  2000,  370  and  100.  These  are  the  limits  of radioactivity prescribed  by these  countries  for  imported foodstuffs. As against these, the prescribed limit for India admittedly is 40 (bq/I). [120C-E]      The analysis  of the  imported  butter  by  the  Bhabha Atomic Research  Centre, which according to the Committee of Experts must  be treated to be accurate, showed the presence in the  samples of  imported  butter  of  CS-137  at  limits ranging from  0.6 Bq/kg to 2.9 Bq/kg. The petitioners relied upon letters  sent by  some internationally known scientists including Nobel  laureates  tending  to  show  that  it  was desirable to  avoid foodstuffs  containing low  level radio- activity which,  according to  them, might  in the  long run prove to  be hazardous.  Those letters were in general terms and only represented a particular school of thought. Surely, the Committee  of Experts  comprising two eminent scientists and an  equally well-known Agro-Economist, was well aware of this point of view. [120E-G ]      The Court  could  not  accept  the  contention  of  the petitioners that  the Court should give a direction that all articles of  foodstuffs using  the  imported  butter  should carry a  label ’Manufactured out of Butter Imported from the EEC countries.’ [120G-H]      The Court shared the opinion of this Court expressed in the Vincent’s  case, where  a direction was sought in public interest for  banning  the  import,  manufacture,  sale  and distribution of  certain  drugs  recommended  by  the  Drugs Consultative Committee  and this  Court  had  observed  that having regard  to the  magnitude, complexity  and  technical nature of  the enquiry involved in the matter and keeping in view the  far-reaching implications  of  the  total  ban  of certain medicines  for which  the petitioner  had prayed, it must be  indicated that  a judicial proceeding of the nature initiated was  not an  appropriate one  for determination of such matters. [121A-C]      The order  of status  quo granted by the High Court was discharged. [121D] 117

JUDGMENT:      CIVIL APPELLATE  JURISDlCTION: Special  Leave  Petition No. 15408 of 1987.      From the Order of the Bombay High Court dated 24.1.1987 in Writ Petition No. 4858 of 1987      Ms. Indira Jai Singh, Anand Grover and Mukul Mudgal for the Petitioners.      K.  Parasaran,   Attorney   General,   Kuldeep   Singh, Additional   Solicitor    General,   A.K.   Setalwad,   A.S. Rajadhyahsha, R.K.  Kulkarni, Ms.  Seita Vaidainathan and P. Parmeshwaran for the Respondents.      Mohan Katarki,  D.B. Vohra, Mrs. Maza Daruwala and L.R. Singh for the Intervener.      The following order of the Court was delivered:                        O  R  D  E  R      This special  leave petition  is directed  against  the

judgment and  order of  the Bombay High Court dated November 24, 1987 declining to issue a writ in the nature of mandamus and other appropriate writs, directions or orders under Art. 226 of  the Constitution as prayed for by the petitioners to direct  the  respondents  to  forbear  from  releasing  7500 cartons (200  MT) of  Irish butter imported into India under the EEC Grant-in-Aid for operation Flood Programme, supplied to the  Greater Bombay  Milk  Scheme  by  respondent  No.  2 National Dairy  Development Board,  on the  ground that  the butter was contaminated by nuclear fallout.      From  the   counter-affidavit  filed   on   behalf   of respondent No.1 Union of India and respondent No. 2 National Dairy Development  Board it  appears  that  soon  after  the Chernobyl disaster  when it  was realised  that the imported milk and  food products  particularly from the EEC countries had the  possibility of  radio-active contamination,  and so the Bhabha  Atomic Research  Centre took  up the matter with the  respective   agencies  and  advised  them  to  get  the representative  samples  for  radio-active  analysis  before releasing them  for public distribution in India. It further appears that  the Atomic  Energy Regulatory Board which is a statutory  body,   has  set  limits  for  radioactivity  for imported foodstuffs.  In disallowing  the writ petition, the High Court observed: 118           "We are  satisfied that  the best scientific brain           available in the country has applied itself to the           question. The  question is  whether in the product           with  which   we  are   concerned  here  there  is           radioactivity above  the permissible  limit.  This           question has  been sought  to be  answered by  the           respondents  on  the  basis  of  laboratory  tests           conducted  on   their  behalf,   Fixation  of  the           permissible limit  of radioactivity  in a product,           naturally, is  for the  scientists to  decide, but           the tests  themselves are  carried on  by  persons           working in  the laboratory, naturally, again under           the guidance  of the scientists concerned. We have           not found  that any  defect is  disclosed  in  the           material which  has been  placed before  us in the           manner of  testing. We  have also  not been  shown           that any  other better  method is  available.  Mr.           Setalvad appearing  for respondent  No. 2 has told           us  that  if  any  other  method  of  sampling  is           suggested the  respondents will  willingly examine           the same and conduct the tests accordingly. "      At one  stage, the  High Court felt disturbed about the concept  of   the  ’permissible  limit’  and  asked  counsel appearing for  both the sides to examine the question in the light of  certain queries which arose in its mind. It wanted to know on what basis the permissible limit of radioactivity was determined,  and in particular, whether this permissible limit had  been determined  on the  basis of  consumption by human beings of any natural food in which radio-activity was present or  was it based upon the external irradication, and added:           "This question  can,  naturally,  be  answered  if           there is  also  answer  to  the  question  whether           natural foods contain re- dioactivity under normal           circumstances."      The High  Court relied upon a letter dated November 13, 1987 from  the Secretary,  Atomic  Energy  Regulatory  Board produced along  with an  affidavit which furnished an answer to the  question. As  regards the contention that the radio- activity that  is  found  naturally  in  articles  of  human

4

http://JUDIS.NIC.IN SUPREME COURT OF INDIA Page 4 of 11  

consumption and  the radio-activity  that is  found in  such articles acquired  by pollution are qualitatively different, and therefore,  the concept  of permissible limit evolved by the scientists  in India should not be accepted, and further that the  permissible limit so evolved based upon studies on article.. for human consumption, which include articles such as Potassium,  was a dangerous concept because Potassium and Caesium-137 have different radio-active properties, 119 the High  Court declined  to be  drawn into  the controversy which was  of a  highly technical nature placing reliance to the words  of caution  administered by this Court in Vincent v. Union  of India, A.I.R. (1987) SC 990. In conclusion, the High Court observed:           "We have already broadly indicated the complicated           nature of  the questions  involved.  We  are  also           satisfied that the authorities concerned are fully           aware of  the problem  at the  highest level. They           have adopted  methods regarded  by  them  as  best           suited-methods  which   have  been   approved   by           scientists. In  these circumstances, we do not see           how  in  a  petition  under  Article  226  of  the           Constitution it is possible for us to resolve this           controversy."      After hearing Ms. Indira Jai Singh, learned counsel for the petitioners,  Shri Atul  Setalvad, learned  counsel  for respondent No.  2 National  Dairy Development Board and Shri Kuldeep Singh, learned Additional Solicitor General at quite some length  on January 20, 1988 this Court having given the matter its  anxious consideration  thought it  desirable  to appoint a  committee of  three experts, namely (1) Professor M.G.K. Menon (2) Dr. P.K. Iyengar and (3) G.V.K. Rao to give its opinion on the following question:           "Whether milk  and dairy  products and  other food           products containing  man-made radionuclides within           permissible levels by the Atomic Energy Regulatory           Board on  27th  August,  1987,  are  safe  and/or,           harmless for human consumption. The Committee of Experts after due deliberation examined the question in  depth and  by its report dated February 19,1988 has expressed  its opinion  that the consignment of imported butter was  safe and  harmless for  human  consumption.  The conclusions reached  by the  Committee can best be stated in its own words:           "1. The  permissible levels  of  radioactivity  in           milk, dairy  and other  food products fixed by the           Atomic  Energy   Regulatory  Board   as  per   its           communication of August 27, 1987 have been arrived           at after due consideration of ICRP does limits for           the General population.           2. The  AERB has  allowed more  safety margin than           other countries,  and international  organisations           like PAO and 120           WHO  in  arriving  at the  levels fixed  for milk,           dairy and  other food products. The levels adopted           by AERB are one of the lowest in the world.           3. The  consumption of  milk, dairy and other food           pro ducts, having levels of man-made radionuclides           below the permissible levels fixed by AERB, by all           sections of  population, and through-out the year,           are safe and harmless." The report of the Committee of Experts shall become and form part of this order.      We have  heard learned  counsel for  the petitioners at

considerable length  on the objections formulated by them in the  counter-affidavit   and  gone   through  the  annexures thereto. We do not find any substance in any of them. In its most recent recommendations, the International Commission on Radiological  Protection   observes  that  ’limits  for  the inhalation or  ingestion of  radioactive material  depend on the concentration  of those  materials  in  limiting  target organs’. The  petitioners in  their  counter-affidavit  have shown different  permissible limits  in different  countries such as  France, U.K.,  E.E.C., and Australia at 3700, 2000, 370  and   100.  These   are  the  limits  of  radioactivity prescribed by  these countries  for imported  foodstuffs. As against this,  the prescribed  limit for India admittedly is 40 (bq/1).  As already  stated, the analysis of the imported butter by  the Bhabha Atomic Research Centre which according to the  Committee of Experts must be treated to be accurate, showed the presence in the samples of imported butter of CS- 137 at  limits ranging  from 0.6  Bq/kg to  2.9. Bq/kg.  The learned counsel for the petitioners read out letters sent in reply by  some internationally  known  scientists  including Nobel laureates  tending to  show that  it is  desirable  to avoid foodstuffs  containing low  level radio-activity which according to  them  might  in  the  long  run  prove  to  be hazardous. What  is remarkable  about these  letters is that they are  in general  terms and  only represent a particular school  of   thought.  Surely,   the  Committee  of  Experts comprising of  two eminent  scientists and  an equally well- known Agro-Economist  was well  aware of this point of view. Lastly, learned  counsel for  the petitioners suggested that the Court  should give  a direction  that  all  articles  of foodstuffs using  the imported  butter should  carry a label ’Manufactured  out   of  Butter   Imported  From   The   EEC Countries’.  We   are  afraid.   the  contention  cannot  be accepted.      In Vincent’s  case, this  Court in  dealing with a case where a direc- 121 tion was  sought in  public interest  for banning of Import, manufacture, sale  and distribution  of certain  drugs which had been  recommended for  banning by the Drugs Consultative Committee, had occasion to observe:           "Having regard  to the  magnitude, complexity  and           technical nature  of the  enquiry involved  in the           matter  and   keeping  in  view  the  far-reaching           implications of the total ban of certain medicines           for which  the petitioner  has prayed,  we must at           the  outset   clearly  indicate  that  a  judicial           proceeding of  the  nature  initiated  is  not  an           appropriate  one   for   determination   of   such           matters." We are of like opinion.      Special leave  petition is dismissed and also the order of status quo granted by the High Court stands discharged. S.L.                                           Petition dismissed Report of  the Committee  appointed by  the Supreme Court in their order of January 20, 1988.       SPECIAL LEAVE PETITION (CIVIL) No. 15408 OF 1987                         ************      The Committee had three meetings.      1.   The first one was held in the room of Prof. M.G.K.           Menon,Member, Planning  Commission, Yojana Bhavan,           New Delhi  on  3  February,  1988.  The  Committee           examined all  the records,  and had  a preliminary           discussion.

    2.   Prof. M.G.K. Menon and Dr. P.K. Iyengar met in the           Tata Institute  of Fundamental Research, Bombay on           8 February, 1988 and had technical discussions.      3.   The Committee had a third and final meeting at the           Raman  Research   Institute,  Bangalor   on   19th           February, 1988.      4.   The Committee  has gone through the paper book and           the documents 122      5.   After  detailed  discussions,  the  Committee  has           adopted the report which is appended herewith.              Sd/-                Sd/-              Sd/-      Prof. M.G.K. Menon   Dr. P.K. Iyengar      G.V.K. Rao                                          19th February, 1988                   REPORT OF THE COMMITTEE Background      The Hon’ble  Supreme Court  by its  order dated January 20, 1988 appointed this Expert Committee to give its opinion to the  Court on  the following  question,  arising  in  the proceedings of  the Special Leave Petition (Civil) No. 15408 of 1987.           "Whether milk  and dairy  products and  other food           products containing  man-made radionuclides within           permissible levels by the Atomic Energy Regulatory           Board on  27th  August,  1987,  are  safe  and/or,           harmless for human con sumption".      1. The  committee examined  in detail the Special Leave Petition,  various   affidavits  and   other   supplementary documents sent  by the  Hon. Court.  The Committee have also deliberated on  the issues  raised by  the petitioners,  and explanations  of   the  respondents  for  understanding  the background of the petition.      2. The  internationally followed practices in radiation protection were  examined, and  it  was  observed  that  the concept of permissible levels of radioactivity and radiation exposure  is  universally  followed  both  for  occupational workers and members of the public. India is no exception.      3. After ascertaining this, the Committee went into the basis used  by Atomic  Energy  Regulatory  Board  (AERB)  in arriving at  the permissible levels for milk, dairy and food products  prescribed   by  the   Board.  It   concluded  its deliberations by  discussing the  specific question referred to the  Committee and arrived at the unanimous opinion given at the end. Scientific Background 123      1. The issues raised and apprehensions expressed by the petitioners arise  from the  fact that  Cherneby  1  reactor accident, which  occured in  USSR in  April, 1986, deposited radioactivity  in   measurable  and  varying  quantities  in several European  countries. Consequently,  the  possibility exists that  milk and dairy products produced soon after the accident   in    such    countries    contain    radioactive contamination. The  specific issue  raised  is  about  Irish butter  imported   into  India   after  the   accident.  The apprehension is  that if such contaminated food products are consumed by  the Indian  population, harmful  effects may be caused.      2. On  the basis  of scientific  information available, the following facts would by the relevant background to take a balanced view on the issues raised.      1. Man has evolved in the background of natural      radioactivity, and atomic and nuclear radiations, which      have been present on the earth since its formation. The      important sources of natural radiation exposures to man

7

http://JUDIS.NIC.IN SUPREME COURT OF INDIA Page 7 of 11  

    have been  continuous cosmic radiations coming from the      Sun and  outer space, natural radioactivity such as due      to K-40,  and to  a lesser  extent due  to uranium  and      thorium and their daughter products in the environment.      The human body itself contains several (of the order of      three) thousands bequerels of radioactivity, mostly due      to K-40.  Exposure to natural radiation sources is thus      unavoidable.           The Cosmic  ray  component  of  natural  radiation      exposure varies with altitude and latitude. Terrestrial      component also  varies  from  place  to  place  due  to      differences in  the concentrations of K-40, uranium and      thorium in  the soils,  Exposure due  to inhalation  of      radon and  its daughters,  from uranium  present in the      soil, varies  even at  the same  place with the time of      the  day   and   season   of   the   year.   Similarly,      concentrations of  natural radionuclides  in food items      vary depending  on the  place where  they are produced.      Thus, the  total exposure  to man  from natural  causes      varies considerably  (upto a factor of 10) in different      parts of India.      2. The  effects of  radioactivity or radiation exposure      in human  beings are  related  to  the  radiation  dose      delivered to  body tissues.  The radiation dose depends      on a  number of  parameters  i.e.  physical  half-life,      energy and  type of  radiation,  biological  half-life,      sensitive body organ etc. 124      3. The effect on human body is, thus, determined by the      above complex  parameters.  The  human  body  does  not      differentiate between  natural and  man-made sources of      radiation exposure as regards their effects.      4. Consequent to the chernoby 1 reactor accident,      radioactive fallout deposited over several European      countries.  Ireland   was   also   affected   by   this      radioactive fallout, though to a smaller extent as      compared to  several  other  European  countries,  e.g.      Sweden, Norway,  Poland, Finland, Switzerland, etc. The      most important  radionuclides so  dispersed were I-131,      Cs-137 and Sr-90. I-131 being a short-live radionuclide      (half-life 8  days) was  of concern  to the   countries      receiving the  fallout, and  not to  India. By the time      imported food items arrived in India, I-131  even if it      was present  when the  item was produced, it  must have      decayed. Strontium-90 being long lived  (half-life   29      years) could have been of concern, but it was deposited      in small  amounts, and  the ratio  of   Sr-90/Cs-137 in      milk observed in European countries was of the order of      1% (UN  Scientific Committee  on the  Effects of Atomic      Radiation draft  report No.  A/AC.82/R. 461 dt. 4.4.87,      relevant papers  annexed to  SLP, Additional  Documents      submitted by  Respondent 2  pp 47-49).  Measurements in      India on  selected dairy product samples also confirmed      Sr-90/Cs-137 ratio  reported by  UNSCEAR to  be in  the      range 0.5-1.5%.  In most  of the  imported milk  powder      samples Sr-90  was below  detection limits.  Therefore,      Cs-137 is  the most  important long-lived  radionuclide      from the  Chernobyl accident; life time of Cs-137 is 30      years. Since it can also be measured in a short-time by      a  sensitive  gamma  spectrometer,  it  is  the.  ideal      radionuclide for   screening of imported food items. It      is for  these reasons  that not only India, but most of      the other  countries also  adopted Cs-137  measurements      for screening of the imported food items.      5. Direct  deposition of radioactive fallout on a grass

8

http://JUDIS.NIC.IN SUPREME COURT OF INDIA Page 8 of 11  

    surface (called foliar deposition) can rapidly transfer      Cs-137 contamination to milk, through the grass-cattle-      milk pathway.  Therefore, in the first few months after      the fallout, there is a greater possibility of milk and      dairy products  from such  areas to be contaminated, as      compared to  other food  items. Of  course,  over  long      periods this  mode of radioactivity transfer is reduced      because once Cs-137 deposits on the soil, its up-take 125      by grass  through roots  is smaller.  In view  of these      facts, milk  and dairy  products become important items      of food which should be carefully measured for possible      contamination.  Since   milk  is  the  staple  diet  of      children, they  are a  particularly sensitive  group of      the population.      6. Even  though milk  and other dairy products are more      susceptible  to   radioactive  contamination   due   to      fallout, amongst  various dairy products, butter oil is      likely to  be less  contaminated with  Cs-137. This  is      because  butter  oil  is  composed  of  fat,  which  is      separated from  the liquid milk fraction in the process      of its  manufacture.  Caesium  compounds  being  highly      water soluble,  almost all of the Cs-137 is left behind      in the liquid portion.      7.  The   International  Commission   on   Radiological      Protection  (ICRP)  is  an  unique  international  non-      governmental  body   of  professionals   from   related      disciplines involved in assessing radiation effects and      recommending guidelines  for the  protection of man and      his environment.  It  was  established  in  1928.  ICRP      recommendations  are  followed  universally.  ICRP  has      defined limits for the general public as 1 mSv per year      averaged over  a life  span, but in any single year, it      should not exceed 5 mSv. The maximum permissible limits      for food  items etc, are derived by each country as per      its national policy, dietary components etc. Therefore,      derived limits  for food  items and dairy products vary      from country to country.      8.  The   Atomic   Energy   Regulatory   Board   (AERB)      constituted by  the Government  of India in 1983 is the      competent authority  for this  country for  radilogical      protection,  and   has  been   empowered  to  prescribe      acceptable limits of radiation exposure to occupational      workers, and  members of  the public,  and  to  approve      acceptable   limits   of   environmental   release   of      radioactive substances.      9. In arriving at maximum permissible limits for butter      oil, milk  and other food products, AERB has considered      ICRP recommendations  regarding  does  limits  for  the      members of  the public  and several other factors, e.g.      sensitive population group, dietary pattern etc. It has      adopted  a   more  conservative   approach  than  other      countries. For  example, out  of 1 mSv/ year does limit      recommended by ICRP, AERB has allowed 126      only 10%  to the  exposure through intake of food items      (0.1 mSv/y).  Further, taking  into account the dietary      pattern in  India and  considering milk,  meat, cereals      and vegetables  as the important constituents of Indian      diet and their daily con sumption by an average Indian,      it has  allowed only 0.013 mSv/y through milk and dairy      products, Therefore,  if the  milk and  dairy  products      containing the permissible level of Cs-137 are consumed      in an  unrestricted manner  throughout the  year by  an      average Indian,  the resulting  does for  one full year

9

http://JUDIS.NIC.IN SUPREME COURT OF INDIA Page 9 of 11  

    would only  be 0.013  mSv, which  is less than the dose      permit ted  by ICRP  by a factor of more than SO. It is      because of  this extra  safety and  caution,  that  the      limits prescribed by AERB, as given in the table at the      end, are  one of  the lowest.  Several other countries,      and agencies  like FAO, on the other hand, have allowed      a higher  portion of  the permitted  dose by ICRP (upto      full 1 mSv/year) to milk and dairy products, and conse-      quently their  permissible limits are higher than those      prescribed by AERB.      10. The  natural radiation  dose varies  from place  to      place in  India by  a factor  of 10,  the average being      around .7  mSv/year. Even at the same place it can vary      by a  factor of  2 and  more in  different seasons. The      biological effects,  if any,  due to the consumption of      food   items    containing   permissible    levels   of      radionuclides     will     be     insignificant     and      indistinguishable, from  those, if  any, due to natural      sources of radiation in the general population.      11. The  concept of permissible levels is not unique to      radio  nuclides.   Such  levels   are   prescribed   by      appropriate agencies  for other  harmful substances  as      well, in  the case  of air  and  water  pollutants  and      contaminants (microbial, chemical etc.).      12. Man-made  radiosotopes like  Cs-137 existed in milk      and  other   dairy  and  food  products  in  measurable      quantities  due   to  atmospheric  testing  of  nuclear      weapons, even  prior to Chernobyl accident. In India, a      net-work of monitoring stations for such food items has      been in  operation at BARC since mid-fifties. After the      cessation of  large scale testing of nuclear weapons in      the atmosphere in 1962, as a result of the partial test      ban treaty,  the levels  of  Cs-137  in  India  started      declining, after  reaching their  highest levels during      1964-65. China and France continued atmospheric testing      of weapons 127      upto 70’s,  though on  a much smaller scale, which gave      rise to  measurable levels of Cs-137 in Indian milk and      dairy products. However, at no time the levels exceeded      the permissible levels prescribed by AERB.      13. As  a consequence of the above monitoring programme      pursued  at   BARC,  very   sensitive   equipment   and      techniques  as   well  as   sampling   and   monitoring      experience  has   accumulated  over  the  years.  AERB,      therefore, entrusted  them with  the task  of measuring      postchernoby 1 samples of imported food items including      milk and  dairy products.  Thus, in  the opinion of the      Committee, measurement  of butter  oil samples has been      entrusted to the most competent agency in the country.      14. The  butter oil is normally used to make up the fat      content of  the reconstituted  milk (6% for whole milk,      for example),  and hence  it will  not form more than a      few per  cent (maximum  6 per  cent) of  the milk to be      distributed to  the public.  The level of radioactivity      in reconstituted  milk will, therefore, be diluted by a      large factor.  Even if  it is  used for  preparation of      ghee as  the end product, the level of radioactivity in      ghee will  not be significantly different, as both have      nearly same  (around 99 per cent) fat content. Thus, no      mechanism is  envisaged by  which the  radioactivity in      the product  meant for  public distribution, using this      butter oil, can get concentrated.      15. The  petition  makes  a  mention  of  sampling  and      measurement procedures  for the  butter oil consignment

    received by  IDC (now  NDDB). In  this connection it is      observed  that   three  sets   of  samples   from   the      consignment have  been measured  at BARC. The first set      comprises of 2 samples collected by IDC, the second set      of 10 samples collected and sent by the Quality Control      officer of  Greater Bombay  Milk Scheme  (GBMS) and the      third set  of  20  samples  collected  jointly  by  the      Quality Control  officer of  GBMS and the scientists of      BARC. Only the first 2 samples showed very small levels      of Cs-137  (2.9 Bq/kg  and 1.3  Bq/kg),  close  to  the      detection level and all the rest showed below detection      levels (detection  level  being  0.6  Bq/kg  of  Cs-137      activity). The  fact that  none of the packages sampled      in the three sets of samples collected have shown any 128      significant amount  of  radioactivity,  with  the  most      sensitive equipment used in BARC, is a clear indication      that it  is most  unlikely that  any of  the  unsampled      packages  are   contaminated   with   Cs-137   to   the      permissible limit set by AERB.           The  procedures  laid  down  by  Indian  Standards      Institution (new called Bureau of Indian Standards) for      materials which  are produced  in bulk  and  packed  in      smaller  volume   elements  should   in  principles  be      adequate. These  procedures have  been followed for the      butter   consignment.    Therefore,    on    scientific      considerations, the  steps taken by the respondents are      satisfactory. OPINION      On a  consideration of  all  the  relevant  facts,  the unanimous opinion  of the Committee on the question referred to it is as follows:      1. The  permissible levels  of radioactivity  in  milk,      dairy and  other food  products  fixed  by  the  Atomic      Energy Regulatory  Board as  per its  communication  of      August  27,   1987  have  been  arrived  at  after  due      consideration of  ICRP  dose  limits  for  the  general      population.      2. The  AERB has  allowed more safety margin than other      countries, and international organisations like FAO and      WHO, in  arriving at  the levels  fixed for milk, dairy      and other food products. The levels adopted by AERB are      one of the lowest in the world.      3. The  consumption  of  milk,  dairy  and  other  food      products, having levels of man-made radionuclides below      the permissible  levels fixed  by AERB, by all sections      of population,  and through-out  the year, are safe and      harmless.             Sd/-               Sd/-               Sd/-      Prof. M.G.K.
