[Late sequelae of exposure to ionizing radiation with various LET's. Effect of dose rate and fractionation on changes in the life span of rats].
In experiments with 2120 albino mongrel rats their life span was followed up after the effect of various types of radiation (for instance, gamma-neutron radiation of 0.9 MeV and gamma- and X-rays) at different exposure schedules (that is, whole-body irradiation with doses from LD0/30 to LD100/30 and fractionated at 24 and 72 hour intervals and dose--rates varying from 0.00042 Gy/min to 1.02 Gy/min). The type of radiation, the dose--rate, single and cumulative doses, the number of fractions and the interval between them were estimated with respect to their contribution to life span shortening.
