title: [Evaluation of the cataractogenic effect of 9 GeV protons].
abstract: A study was made of the regularities of formation of lenticular opacity in mice exposed to 9 GeV protons and 60Co-gamma-rays. The RBE coefficients, calculated by the nonparametric method, were found to depend upon dose and time after irradiation. It was shown that after small radiation doses (0.25 to 0.50 Gy) the RBE coefficients increased from 1 to 8 with increasing period of observation. With higher doses (up to 5.0 Gy) the RBE coefficient increase in time was less pronounced.
