when cells were x-irradiated and immediately followed by 0.5 m nacl/pbs treatment for 20 min at 37 degrees c , cell survival was significantly decreased and a concomitant increase in the number of mutants was observed , indicating that postirradiation treatment with anisotonic salt solution caused conversions of potentially lethal damage and potentially mutagenic damage to lethal and mutagenic damage , respectively .
