Tamplin » The following is my analysis of the origin of sos soft tissue sarcoma that ultimately resulted in his “death and of the Consultation Report, submitted by Dr. Niel Wald, dated Jan. 29, 1973. . unloaded, rotated, and loaded a crate containing a leaking carbov of plutonium-239 (Pu-2393) solution. .This could not have occured without contaminating the palmar surface of his left hand, which was bare. The question is: @id this Pu-239 ccntamination cause to eevelop a Sarcoma? Since radiation induced cancers are identical with those that occur spontanecusly, it is necessary to consider the relative chances that the cancer was spontaneous or Pu-239 induced. The United States Vital Statistics, record a death rate for malionant neoplasms (other than melanoma) of the skin in the upper extremity of less than one per million per year. Since synovial sarcoma is a rare form that often metastasizes and hence has a poor procnosis, its occurrence rate is certainly ‘less than the total skin. cancer death rate of one per millicn per year. Thus it is highly unlikely that anyone whe handled this crate would ‘spontaneously develop this sarcoma en the contaminated hand (less than one chance in a million). Now let us consider what the chances are of the develop- ment of cancer as a result of plutonium contamination of the skin. Experimental data from plutonium contaminated animals demonstrate that injection of 1 microgram of Pu-239 into the skin of rats prometiy 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. This is reason to suspect, since the volume of liquid was reduced, the Pu was actually more concentrated in 1963. But setting “that _ aside, one drcp would be expected to contain between 8 and 16 micrograms of Pu-239. One-one hundredth of a milliliter (@ very small amount of liquid) would have been sufficient to r _ PRIVACY ACT MATERIAL REMOVED ”
