RAPID DETERMINATION OF MIXED BETA-GAMMA RADIONUCLIDES IN URINE
Journal Article

· Health Physics (England)
A bio-assay procedure was developed which enables a rapid estimation of the total amount of beta - gamma emitting isotopes in a urine specimen. The beta - gamma emitting radionuclides are coprecipitated from urine on an ammoniacal alkaline earth phosphate precipitate. The filtered precipitate is fired in a muffle furnace, dissolved, and directly plancheted. The planchet is both beta - and gamma -counted. The recoveries of strontium-89, strontium- yttrium-90, zirconiumniobium-95, cerium- praseodymium-144, iron-59, chromium-51, and zinc-65 are greater than 90%. Cobalt has a recovery of 85%. (auth)
