X-rays Low Dose Relationships within the G2 Phase of Chinese Hamster Cells

Part of the NATO ASI Series book series (NSSA, volume 124)


Heterogeneous chromosomal radiosensitivity was found in the G2 phase of a newly established cell line (line 19/1) of Chinese hamster (Cricetulus griseus, 2 n = 22) during the first five-hour testing period after 100 cGy x-irradiation. Metaphases showed maximal aberration frequencies when they were fixed in the first or fourth hour after irradiation. Dose effect correlations for the first hour colchicine collection time show between 5-100 cGy irradiations significantly more aberrations than non-irradiated control cells within the lowest radiation dose of 5 cGy too.
