摘要：
The elemental composition of the material of beryllium blocks of SM reactor reflector in the initial state was determined by inductively coupled plasma atom emission spectrometry (ICP AES). The alpha-, beta-, and gamma-active components of the radiation from Be irradiated to a neutron fluence of 6 x 1022 cm(-2) (E > 0.1 MeV) were determined. Radiochemical analysis revealed the presence in the irradiated Be of Co-60, Mn-54, Cs-137, Cs-134, and Sr-90. The following alpha-emitters were revealed: Pu238-241, Am-241, Am-243, and Cm-244.
