INAA was applied for searching more effective biosorbents for U and Ag among 9 and 47 strains of actinomyces, respectively. Biomasses of strains were tested for the Ag and U sorption capacity from model solution, containing 50 mg/l Ag ions and from technological solution of U-production, containing 7.11 mg/l U ions. The U and Ag samples were irradiated for 5 hours and 20 hours, respectively, at a neutron flux density of 5.3
. 1013 n. cm- 2. s-1 . The Ag content was calculated from the gamma-line of radionuclide110m Ag (T1/2 = 250.4d,Eγ = 657.7keV). The U content was calculated from the gamma-lines (228.2 keV, 277.8 keV) of radionuclide239 Np (T1/2 = 2.35 d). The error of U and Ag determination (relative standard deviation) was 2-3%.
