Description

The biological effectiveness of two cyclotron-produced fast neutron fields (E/sub n/ approximately 3.5 and 7 MeV) has been studied as a function of depth within a water phantom. Aerobic and hypoxic HeLa S3 cell survival data were obtained at depths of 2 and 12 cm and compared with those measured in a 60Co gamma ray field. Although the resulting survival curves show a small decrease in sensitivity with increasing depth, the oxygen enhancement ratio remains constant and has a value of 1.8 +- 0.1 in both fields. (U.S.)
