Bains, M E.D.

Methods were developed for the determination of plutonium alpha activity in urine, feces, and biological materials. The chemical stages involved give practically complete separation of all extraneous material from the plutonium, which is electrodeposited on to a 0.5-in. stainless steel disc to produce a thin high-resolution source. The limit of detection is 0.025 mu mu c/sample (sixteen-hour count) when the sources are counted in a small scintillator counter, but is lowest when counted in a counter which counts particles of energy 5.05 to 5.25 Mev only, and which therefore discriminates against small quantities of alpha active materials introduced with the reagents in the final electrodeposition stage of the process.
