The RBE of Cf-252 neutron irradiation was determined for hemopoietic tissue using spleen CFU-S. Radiosensitivity was compared to acute Cobalt-60 radiation and low dose rate Cesium-137 under identical irradiation conditions. The RBE for the neutron component of the Cf-252 radiation was 2.1. No dose rate effect was observed for hemopoietic CFU-S to acute doses or low dose rate photon irradiation.
