Determination of the Kerma in Biological Tissue with Gadolinium Irradiated by the Epithermal Neutron Beam in VVR–SM Reactor at the Institute of Nuclear Physics of the Academy of Sciences of Uzbekistan

The kerma in biological tissue with gadolinium under irradiation by epithermal neutrons in a special channel of the VVR-SM reactor at the Institute of Nuclear Physics of the Academy of Sciences of the Republic of Uzbekistan is determined. The neutron kerma rate is found to be $$ K_n^{\mathrm{b}.\mathrm{t}} $$ = 1.35 · 10–4 Gy/sec for biological tissue and $$ K_n^{\mathrm{Gd}} $$ = 3.1 · 10–7 Gy/sec for 1 μg of natural gadolinium in 1 g of biological tissue.
