Abstract: The efficiency of isolation of ¹³⁷Cs from biol. material by extn. using Co dicarbolide-H⁺ (I) was compared with the absorption on Co(II) ferrocyanide, on Cu(II) ferrocyanide, and on NH₄ molybdophosphate. Extn. of ¹³⁷Cs (by dicarbolide) appeared to be the best among these procedures. The influence of preanal. treatment of samples on the yield of ¹³⁷Cs by extn. using dicarbolides of Co(II) (either I or a chlorinated deriv.) and its influence upon the decontamination efficiency of the isolation procedure were detd. Analyses were made of tissue samples with in vivo incorporated radionuclides ¹³⁷Cs, ⁶⁰Co, ⁶⁵Zn, ⁹⁵Zr, ¹⁰⁶Ru, and ¹⁴⁴Ce either dild. in mineral acid only, or mineralized (ashed) by both the wet and dry method. A procedure is suggested for isolation and radiometric detn. of ¹³⁷Cs in tissues contg. radionuclide mixts.
