Effects of a prolonged irradiation with low dose-rate ionizing radiation on the hemopoiesis of mice

Description

SPF C3H/HeN female mice were irradiated with 137Cs γ-rays at doses of 1-8 Gy at the dose rate of 20 mGy/22 h/day. After irradiation, the numbers of CFU-S and CFU-GM in the bone marrow were determined. Number of peripheral blood cells was also counted. The day 12-CFU-S, which is in the earliest stage of differentiation, decreased as the dose increased. Decreases in the numbers of day 7-CFU-S and CFU-GM were also observed. Regardless of the severe decrease in the number of hemopoietic stem cells, no remarkable changes were observed in the number of peripheral blood cells, indicating an enhanced differentiation of the precursor cells.
