Kinetics of disappearance of kidney blood cell lineages following lethal irradiation. (A) Light scatter profiles of whole kidney marrow showing the effects of 40 Gy on the relative percentages of erythrocytes (red gate), lymphocytes (blue gate), precursors (pink gate), and myeloid cells (green gate) over time. (B) Absolute cell counts of each leukocyte subset over time. The numbers of each population decreased to their low points by day 6 and did not subsequently recover before death.
