Following irradiation with monoenergetic neutrons of 15.1, 1.91, 0.43, and 0.23 MeV, cells of broad bean roots are delayed in progression through the cell cycle. There is an exponential relation between cells progressing (''surviving'') into mitosis and dose over a range of time periods. Relative biological effectiveness (RBE) increases with decreasing neutron energy and the two lowest energies are similar in effect. The RBE-neutron energy dependence for this largely transitory delay phenomenon in general approximates that found for permanent radiobiological endpoints, possibly indicating that this effect depends on the square of the energy absorbed in sites of nuclear size or smaller.
