Myeloid Leukemia in Male RFM Mice Following Irradiation with Fission Spectrum Neutrons or γ Rays

Abstract
The induction of myeloid leukemia following fission neutron irradiation was examined over the 0-80 rad dose range. Over this dose range the dose response could be described by the linear regression equation: y = 0.94 + 0.18X. A comparison of these data with data obtained following γ irradiation from this study and a previous study indicated that the relative biological effectiveness for myeloid leukemia induction was 2.8. These results appear to be compatible with those reported by other investigators.
