The lethal and mutagenic effects and the nature of mutations induced by 90Sr-90Y and 89Sr in cells of the yeast Saccharomyces cerevisiae were studied. The lethal efficiency was determined for 89Sr as (7,6 +/- 1,05) X 10(-5) decay-1, for 90Sr-90Y-(3,3 +/- 1,6) X 10(-4) decay-1. The mutagenic efficiency for ade1 and ade2 genes was determined for 89Sr as (8,3 +/- 2,5) X 10(-9) decay-1, for 90Sr-90Y-(2,9 +/- 1,5) X 10(-8) decay-1. For ade2 locus, the spectrum of mutations induced by 89Sr was a follows: one deletion, 17% of frameshifts and 83% of base pair substitutions--51% of transversions, 22% of GC-AT transitions and 10% of AT-GC transitions. The data of the present work suggest that 90Sr-90Y and 89Sr are very efficient physical mutagens. The relative mutagenic efficiency (RME) was estimated for radionuclides studied.
