The negative results on the clavicle specimen are also equivocal. -The issue here is a small quantity of Pu-239 thet remained Localized in the palmar area cf the left hand. This bone specimen indicutes oniy that the amount of system- ically absorbed Pu-239 was too small to be detected in this bone specimen. None of these clinical findings are able to set aside the strong possibility that ~ ' result of the plutonium contamination. sarcoma was a direct The most likely course of events is that a small quantity of the Pu-239 solution {less the 0.01 milliliter) was deposited in the tissue below palm. This may have occured through a small cut or via a sliver. The body then reacted to this material as a foreign body, and encapsulated it. Eventually, a lesion Similar to that discussed in Exhibit 2 developed. This nodule’. progressed beyond the precancerous stage to become an infiltrating soft tissue sarcoma.
