Recovery of the hemopoiesis in mice after continuous irradiation with a dose rate of 0.957 Gy/d and a total accumulated dose of 19.14 Gy. 1

The evaluation of histological changes in bone marrow, spleen and thymus of mice after continuous irradiation with a dose rate of 0.957 Gy/day and a total accumulated dose of 19.14 Gy are reported. Erythropoiesis in the spleen could be recovered quickly, significantly exceeding the spleen erythropoiesis of the controls on the seventh post-irradiation day. Myelopoiesis in the bone marrow could be recovered until the 21st day and erythropoiesis until the 28th day after the end of irradiation. Lymphopoiesis in the thymus could be recovered on the 28th day approximately and in the spleen roughly on the 60th day after the end of irradiation. (author)
