Global determination of alpha emitters (241Am, 237Np, 239Pu, 232Th) in biological media (urine and feces)
Description
A technique is described in this paper which permits the determination of the gross alpha activity emitted by a mixture of specially radiotoxic elements in urine and feces. After reduction and adjustment of the solution at pH 5,0, the radionuclides are adsorbed on glass marbles. The elution is made in acid medium (HCl 6N). Under these conditions the chemical yields are very satisfying: 96+-6% for urine and 68+-9% for feces. In case of significant results at the end of the manipulation, the radioactive source quality is sufficient to allow the identification of the contaminating radionuclide(s) by alpha spectrometry

La technique mise au point permet le dosage global d'un melange d'emetteurs α particulierement radiotoxiques dans les urines et les selles. Apres reduction et ajustement du pH de la solution a 5, les radionucleides sont adsorbes sur des billes de verre. L'elution est faite en milieu tres acide (HCl 6N). Dans ces conditions les rendements chimiques obtenus sont tres satisfaisants: 96+-6% dans les urines et 68+-9% dans les selles. La qualite des sources obtenues en fin de manipulation est suffisamment bonne pour qu'en cas de resultat significatif, le ou les radionucleide(s) contaminants puissent etre identifies par spectrometrie αFiles
