Abstract
Induction of cell killing and mutation to 6-thioguanine resistance was examined in a radiation-sensitive mutant strain LX830 of mouse leukemia cells following .gamma. irradiation at dose rates of 30 Gy/h (acute), 20 cGy/h (low dose rate), and 6.2 mGy/h (very low dose rate). LX830 cells were hypersensitive to killing by acute .gamma. rays. A slight but significant increase was observed in cell survival with decreasing dose rate down to 6.2 mGy/h, was not significantly different from that for moderate or acute irradiation. acute irradiation.This publication has 13 references indexed in Scilit:
