[A decrease in the efficiency of radiation damage repair in HeLa tumor cells with their preliminary irradiation at low radiation doses (0.1 Gr)].
In experiments with tumor HeLa cells, a study was made of the survival rate of both the whole population and individual clonogenic cells after irradiation within different regimes at a cumulative dose of 4 Gy. The results obtained prompt a conclusion that the preirradiation with a dose of 0.1 Gy decreases the efficiency of repair of radiation-induced damages to cells.
