28878 Mr. 2. Kratzen Dr. Delpla is surprised that such small doses could have resulted in such heavy damage. He is wondering if the doses have not been greatly underestimated; he indicates that pople subject to radiation have lived without precaution and for almost 48 hours in a very heavily contaminated atmosphere (1 R/h at one meter above ground level when first aid arrived). He is asking if those people are not subject historically and spontaneously to nodules in the thyroid. Dr- Delpla would like to know also what did happen to the Japemese fishermen after they were subject to similar fall-out. Very Sincerely Yours, a ae D.C. DCL: sb . f ae ! , Meo. Ly UALR LEFEBVRE
