Long-term exposure of /sup 238/PuO/sub 2/ to a terrestrial environment
In many space missions that use radioisotope thermoelectric generators, /sup 238/PuO/sub 2/ is used as the source of heat. We exposed some of this heat-source material to simulated terrestrial environments for an 8-yr period. During this time we monitored the release of plutonium to water, air, and soil. Plutonium was found in the air, especially after the beginning of a rain, and in the water that percolated through the soil after a rain, but the major part of the plutonium was held in the soil.
