BS>Two lines of mice, showing significant differences in response to daily exposures to 100 r x rays, were exposed to brief daily irradiation with 42 plus or minus 4 rads of fission neutrons. Mice of the sixth selected generation were irradiated seven times a week with fission neutrons at Argonne National Laboratory's CP-5 Research Reactor. The mean survival time of the low-resistant line was 21.8 days and that of the high-line was 26.8 days. The two selected lines showed simiiar differences in survival under daily doses of 100 r x rays and under daily doses of 42 rads fission neutrons. The assumed value for RBL (2.5) appeared to be approximately correct. No significant differences in survival times could be established between males and females in the neutron- irradiated mice. Male mice, of both lines, showed a positive correiation between preirradiation body weight and survival time. (auth)
