This could not have occured without contaminating the palmar surface of his lert hand, which ras bare. The question 1s: 42d this Pu-239 contamination cause ~ to develop a Sarcoma? Since radiation induced cancers are identical with those that occur spontaneously, it is necessary to consider the relative chances that the cancer was spontaneous or Pu-239 induced. The Jnited States Vital Statistics, record a death rate for malicnant neovlasms (other than melanoma) of the skin in “a upper extremity of less «han one per million ver voar. Since Synovial sarcoma is a rare form that often metastasizes and hence has a poor proanosis, itS occurrence rate is certainly less than the total skin cancer death rate of one per million per year. Thus it is highly unlikely that anyone who nandled this crate would spontaneously develop this sarcoma on the ncaminated hand (less than on2 chance in a mililicn). yvow let us consider what the chances are of the development of cancer as a result of plutonium cortamination qf the skin. Experimental data from plutonium contaminated animals a -monstrate that injection of 1 microgram of Pu-23%9 into tne skin of rats promptly produced cancer in up to 5% of the animals (Exhibit 1). The particular tumors are fibrosarcomas. Now the analysis done by LASL indicated that the Pu-239 concentration was about 160 micrograms per milliliter. is reason to suspect, Since the volume of liquid was the Pu was actually more concentrated in 1963. aside, one drop would be This reduced, But setting that expected to contain between 8 and 16 micrograms of Pu-239. One-one hundredth of a milliliter (a very small amount of liquid). would have been sufficient to on PRIVACYACT MATERIALREMOVED
