Survival of mouse L-929 cells following neutron irradiation

Mouse L-929 cells were exposed in a monolayer to x rays and to a 3.5 MeV neutron beam for comparison of damage effects. Single dose experiments showed a radiobiological effectiveness of 1.5 for neutrons when compared to x rays. Both single and paired dose experiments indicated that the cells were unable to repair neutron-induced damage. Dinitrophenol was found to increase the survival of those cells irradiated with neutrons.
