In this event, his chance of develoving cancer would be one in twenty. This is at least 50,000 times higher than his chances of develoniny tie cancer spontaneously. In other words, the evidence is overwhelming in favor of the tumor resulting from Pu-239 contamination. The above relative probability is based upon data from animals. It is quite pussible that man is more sensitive tnan “rnimals to cancer induction by Pu-239. In fact, the biolocica evidence strongly suggests that man is more sensitive. Exhibit 2 is a case report of a nodule removed from a man. This nodule -ontained only 0.08 ug of Pu-239. Commenting on the histological eyamination of the lesion, the authors states,"The autoradiographs showed precise confinement of &-tracks to the area of maximum damage and their penetration into the basal areas of the epidermis, where epithelial changes radiation exposure were present. typical of ionizing The cause.and effect relation- ship of these findings, therefore, seemed obvious. lesion was minute, the changes in it were severe. Although the Their similarity to known precancerous epidermal cvtoloaic changes, cof course, raised the question of the ultimate fate of such a 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 surrounding tissue was very intense. There is every reason to believe “Sat a smaller quantity cl Pu-239 would heve prodceced similar changes. , When I consider the above human and animal data together with the relative probability of 50,000, I can come to no other ‘anclusion than that this sarcoma was a direct result of the contamination of left palm by Pu-239. Turning now to Dr. Wald's Consultation Report, it can be stated that he has presented no evidence to disprove the claim 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 Report submitted by Anson M. Bartlett on April 11, 1963, pages 29-30, the The single urine and feces January 19 examination was conducted not on his home, clothing and automobile. PRIVACY ACT MATERIAL REMOVED ‘, but on
