The hypothesis that cisplatinum (c-DDP) interacts with radiation by inhibiting the cellular repair capacities, was tested by comparing the interaction of c-DDP with low-LET (60Co gamma-rays) and high-LET radiation (d(50) + Be neutrons) in mice. The biological endpoint was lethality, 6 days after total body irradiation (early intestinal tolerance). The dose modifying factor was 1.80 +/- 0.25 for c-DDP plus 60Co gamma-rays, and 1.97 +/- 0.3 for c-DDP plus neutrons. As less repairable damage is induced by fast neutrons than by photons, this suggests that, in this system, the interaction between radiation and c-DDP is not explained by repair inhibition but is purely additive.
