Abstract
Early repair (Elkind repair) kinetics of an early and a late responding tissue after gamma and d(50) + Be neutron irradiation were compared in mice. LD50 at five days after abdominal irradiation and LD50 at 180 days after thoracic irradiation were chosen as biological endpoints to study intestinal and lung tolerance, respectively. Elkind repair is assessed from the additional dose Dr to reach LD50 when a single dose Ds is split into two equal fractions Di separated by time intervals "i" ranging from 0 to 24 hours (Dr = 2Di-Ds). Dr is greater for lung than for intestine after both gamma and neutron irradiations. Our data are consistent with an exponential early repair with an half-life (T 1/2) of 0.5 h for intestine and 1.5 to 2 h for lung.
