Data are presented on the mean after survival of female B6CF1 mice exposed to single doses of neutrons (1 to 40 rad) or gamma rays (22.5, 45, and 90 rad). For gamma-ray exposures and for neutron exposures up to 10 rad, the dose-response curves are indistinguishable from linear; higher neutron doses produce significant departures and linearity. Consequently, in these data, an upper limit of the relative biological effectiveness (RBE) exists for life shortening from all causes of death after single neutron exposures; this value is 15.0 +/- 5.1. The RBE depends on the cause of death, ranging from 2 to 5 for lymphoreticular tumors to 23-24 for lung tumors.
