[The action of low doses of gamma radiation on mammalian cells].
Effect of gamma irradiation in low doses (10, 20, 40 and 50 cGy) on HeLa cells was studied. The survival of cells exposed to the irradiation in the dose of 50 cGy was decreased while it remained unchanged in cells irradiated in the dose of 10-40 cGy and their descendants. Nonetheless, their survival following an additional treatment with a mixture of cytosine arabinoside and hydroxyurea was reduced. It was suggested that the genome stability was diminished in irradiated cells and their descendants.
