Abstract:
Induction of chromosome aberrations in G0 lymphocytes of peripheral human blood exposed to 235U and d(50)+Be neutron radiation was studied. Dose--effect relationships for different types of chromosome aberrations were analyzed. Linear dependence of the effect was established for the studied neutron radiation, except for the yield of dicentrics exposed to d(50)+Be neutrons. Accordingly to the yield of dicentrics, the relative biological efficiency (RBE) of 235U and d(50)+Be neutrons was 19.5 and 4.14, respectively.
