摘要

Relationships are provided to compute the decreasing plutonium content and changing isotopic distribution of plutonium materials for the radioactive decay of exp 238 Pu, exp 239 Pu, exp 240 Pu and exp 242 Pu to long-lived uranium daughters and of exp 241 Pu to exp 241 Am. This computation is important to the use of plutonium reference materials to calibrate destructive and nondestructive methods for assay and isotopic measurements, as well as to accountability inventory calculations.
