Cell inactivation effects of fast neutrons produced by NIRS cyclotron on murine lymphoma (L5178Y) cells in vitro

Description

Cell inactivation effects of x- and fast neutron irradiation on murine lymphoma L5178Y cells were investigated by means of soft agar colony formation technique. The fast neutrons were produced by 9Be(d, n) B10 reactions at dE of 30 MeV in NIRS cyclotron. X-ray survival parameters were Do=88.8 rad, Dq=115.4 rad, and n=3.6 and that of fast neutrons were 65.5 rad, 66.8 rad and 2.8 respectively. Relative biological effectiveness (Do ratio of fast neutrons against x-rays) was calculated to be 1.33. A great decrease in Dq dose after fast neutron irradiation suggests decreased capacity of sublethal damage in the cells and thereby only small fraction of cells could recover. (auth.)
