Abstract
Cellular suspensions of S. cerevisiae were exposed to X- and gamma-radiations of 3 different qualities simultaneously. Absorbed dose in rads for each radiation was determined to 3%. Counts of developed macrocolonies provide a logarithmic dose-survival curve (after correction for radioresistant budding cell population). The ratio of the slope of the test radiation survival curve to that for the standard 200-kvp radiation is used as a measure of relative biological effectiveness (RBE). The average RBE of 5 experiments was found to be 0.85 [plus or minus] 0.05 for both cobalt-60 gamma-rays and 22 Mevp X-rays; no significant difference between these 2 supervoltage radiations being demonstrated.Keywords
