[The possibility of using the population characteristics of myelokaryocytes for the early diagnosis of radiation lesions].

The method of flow cytofluorimetry was used to study some population characteristics of bone marrow cells of control and irradiated rats. The simultaneous recording of cellularity and distribution of myelokaryocytes among the cell cycle phases was shown to give reliable results for determining the extent to which the organism was exposed at early times following irradiation.
