[Radiosensitivity of Ehrlich ascites carcinoma clonogenic cells irradiated with Co60 gamma rays in hypoxic conditions].
A study was made of the survival rate of Ehrlich ascites clonogenic cells on the 7th day following inoculation depending on 60Co-gamma-radiation dose delivered under hypoxic and oxygenating conditions in vitro. In both cases the survival curves had a small shoulder and an exponential part. The oxygen enhancement ratio determined as a ratio of D0 for hypoxic (6.59 Gy) and oxygenated (2.06 Gy) cells was 3.2.
