ABSTRACY By measuring the survivals of HeLa cells, DNA strand breaks and the activity of O,6,-methylguanine DNA methyltransferase, the biological effect of γ-rays and MNNG on HeLa cells was investigated. It was observed that the combined exposure of γ-rays and MNNG increased the cell lethality, DNA strand breaks and the inactivation of the O,6,-methylguanine DNA methyltransferase. The decrease of the survival curve parameters D,0, D,q, shown a synergism between γ-radiation and MNNG.
