Cumulative effect of nonstandard radiation.
Experimental data on cumulative effect of nonstandard beams are evaluated and analyzed in terms of cell kinetic model. The dependence of RBE on the dose per fraction is derived. The repopulation is shown to diminish RBE. The ratio of RBEs for late and acute injury is discussed. The "neutron TDF" proposed for clinical purposes is criticized.
