In this paper, a stochastic model of cell survival, which was developed by Cotlet and Blue, based on the work of Jones, is extended to describe bone marrow cell survival in high dose rate radiation fields with arbitrary neutron to gamma‐ray absorbed dose rate ratios. Mathematical formulas are obtained that describe the interaction of the neutron and gamma‐ray components of the absorbed dose, for radiation fields with arbitrary neutron to gamma‐ray dose rate ratios, for exposures of cells to various absorbed doses, at various high dose rates.
