[The cytogenetic effects of 22-MeV neutrons]

22-MeV neutrons affecting the culture of human peripheral blood lymphocytes have been studied for their cytogenetic peculiarities. Linear character of the dependence of chromosome aberrations yield within the dose range of 0.2-4.0 Gy is noted. Relative biological efficiency of 22-MeV neutrons reaches the highest values at low doses (18.8-2.4). Pair fragments and dicentrics prevail in spectrum of aberrations.
