Determination of plutonium in feces and urine.
A method was developed for the determination of plutonium (239Pu, 238Pu, etc.) in feces and urine excreted by persons for 24 h. Plutonium is successively separated from inorganic macrocomponents present in samples and from other alpha emitters by the help of coprecipitation with BiPO4, LaF3 and extraction with TTA. After separation, the electrodeposition of plutonium on stainless-steel discs can be carried out. The chemical yields of separation of plutonium are about 80%.
