title: [The mutagenic action of gamma radiation on Chinese hamster cells. The cytogenetic characteristics of the mutants at the HPRT locus].
abstract: The peculiarities of mutation induction and cytogenetic characteristics of spontaneous and radiation-induced HPRT mutant clones have been studied. The linear-quadratic dependence of the mutation induction on radiation dose has been found. High heterogeneity of cytogenetic parameters (aneuploidy and chromosome aberration frequency) has been shown in the mutants.
