[Sensitivity of DNA synthesis to gamma-irradiation in Ehrlich ascites carcinoma cells in stationary and logarithmic growth phases].
A study was made of the influence of gamma-radiation on DNA synthesis in cells of 3-day and 7-day Ehrlich ascites tumor cultures. DNA synthesis in cells of the 3-day culture was more sensitive to moderate radiation doses than those of the 7-day culture as was observed during the first 30 min after irradiation. After 3-hour postirradiation incubation, no appreciable difference was noted in radiosensitivity of DNA synthesis in the cells of the 3-day and 7-day cultures.
