The above relative probability is based upon data from It is quite possible that man is more sensitive than animals. animals to cancer In induction by Pu-239. fact, the biological evidence strongly suggests that man is more sensitive. Exhibit 2 is a case report of a nodule removed from aman. This nodule contained only 0.08 ug of Pu-239. Commenting on the histological oF ‘examination of the lesion, the authors. states,"The autoradiographs showec precise confinement of K-tracxs to the area of Maximum damage and their penetration into the basal areas of the epidermis, where epithelial changes typical of ionizing radiation exposure were present. ship of these findings, therefore, The cause and effect relationseemed obvious. lesion was minute, the chances in it were severe. Similarity to known precancerous epidermal Althougn the Their cytologic chances, of course, raised tne question of the ultimate fate of sucha lesion should it be allowed to exist without surgical intervention..." In this case, less than 0.1 ug of Pu-239 produced precancerous changes in human tissue. The dose to the surroundcine tissue was very intense. There is every reason to believe that a smaller quantity of Pu-239 would have produced similar changes. When I consi@er the above human and animal data together with the relative probability of 50,000, conclusion then contamination of Turning now that this I can come to no other sarcoma was a dircct result of the left palm by Pu-239. to Dr. Wald's Consultation Renrourt, it can be Stated that he has presented no evidence to disprove the clain that this sarcoma was caused by Pu-239 contamination. I shall discuss Dr. Wald's report in the order that it was written. According to the Division of Inspection Peport submitted by Anson M. Bartlett on April 11, 1963, pages 29-30, the January 19 examination was conductcd not on but on his home, clothing and automobile. The single urin2 and feces PRIVACY AGT MATERIAL REMOVED
