A comparative study of RBE (relative biological effectiveness) of ..cap alpha.. irradiation of yeast cells that multiply by division revealed that the survival curves after exposure to both ..gamma.. and ..cap alpha.. radiation are sigmoidal at the stationary phase of growth; at the logarithmic phase, the survival curve referable to ..gamma.. radiation is sigmoidal and that referable to ..cap alpha.. radiation is exponential. The RBE of ..cap alpha.. particles at the stationary phase of growth changed from 5.0 to 7.0 with delivery of doses of 10 to 180 krad. At the logarithmic stage, RBE rose sharply from 3.2 to 14 in the range of low doses of radiation. The possible causes of difference in relationship of RBE to dosage in the stationary and logarithmic phases of growth are discussed.
