  • Title: [Development of radiation injuries and recovery processes in the hematopoietic tissue of mice after repeated exposure to fast neutrons and gamma-irradiation].
    Author: Ul'ianova VA, Shafirkin AV, Farber IuV, Markelov BA.
    Journal: Radiobiologiia; 1987; 27(4):510-5. PubMed ID: 3628732.
    Abstract:
    A study was made of the number of CFUs and karyocytes in thigh bone and the concentration of functional cells in the peripheral blood of mice subjected to fast neutron- and gamma-irradiation four times at a 60-day interval (210 cGy per fraction). The regenerating potential decreased and the half-recovery time T1/2 increased in the haemopoietic tissue as the number of fractions and total absorbed dose increased. The dependence of T1/2 on the equivalent radiation dose was as follows: T1/2 = T1/2(0)e0.0009D.
