[Action of mixed gamma-neutron radiation with various dose rates on the number of cells in thymus and chromosomes of mice bone marrow and human lymphocytes].
The irradiation with mixed gamma-neutron radiation was carried out at the pulse nuclear reactor on fast neutrons BARS-6 in a regimen of one pulse (100 micros) and in a regimen of continuous irradiation during 60 minutes. Was shown, that the irradiation of mice with pulse radiation was 1.3-1.8 times more effective in the induction of the chromosome aberrations in bone marrow cells in comparison with the continuous regimen of irradiation. At the same time, other biological tests (yield of chromosome aberrations in human lymphocytes, decreasing the number of cells in thymus) demonstrated that pulsed and continuous regimens have almost equal biological effectiveness.
