- Abstract
Biological efficiency of ion beams and neutral particles can be determined by studying the number of chromosome aberrations induced in irradiated cells. In the present investigation, we studied Relative Biological Efficiency (RBE) and statistical distributions of chromosome aberrations induced in human peripheral blood lymphocytes exposed to 0.23 Gy and 0.47 Gy of 252Cf neutrons. Due to the possible cell cycle delay, the aberrations were scored at two different sampling times. Data were fitted using Poisson and Generalized Poisson distributions. In all cases, experimentally measured distributions significantly deviate from theoretical expectations.
