Depression of Tracer Ion Uptake Curve in Rat Erythrocytes Following Total Body X-Irradiation

Summary 1. A method of demonstrating the depression of the erythroid portion of the bone marrow by x-irradiation with the use of Fe59 is presented. 2. Graphs of the red cell FeS9 uptake curve in rats at various dosage levels of total body x-irradiation and at varying times after irradiation are given.
