[Repair of chromosome damage in human lymphocytes after fractionated irradiation with fast neutrons]

The frequency of chromosome aberrations in nonstimulated lymphocytes of the peripheral human blood was shown to change after fractionated neutron irradiation of mean energy of 6.0 MeV. At a 2-hour interval between exposures, the number of aberrations exceeded, and at 5-6-hour interval was less than that induced by a single exposure at the same dose.
