Induction of gene and deletion mutations by accelerated heavy charged particles in Escherichia coli cells

The results of the induction of the point and the deletion mutations by the radiation with broad region of linear energy transfer (LET) ox Escherichia coli cells. The linear-quadratic function for point mutation induction was shown in comparison with linear dependence for deletion mutations. The relative biological effectiveness (RBE) is described as a function of LET by dependence with a local maximum. The greatest RBE coefficients for the lethal effects, gene and deletion mutation induction realize under different LET of heavy charged particles.
