[Effect of low-level chronic x-rays on the hemolytic stability and population composition of peripheral blood erythrocytes].

A study was made of the haemolytic stability and population composition of peripheral blood erythrocytes of rats chronically exposed to X-radiation of 0.258 mC/kg/day during 30 days. Haemolytic stability of erythrocytes changed at cumulative doses of 2.58, 5.16 and 7.74 mC/kg. Percentage of some erythrocyte fractions obtained by fractionation in a sucrose density gradient was found to change after irradiation with cumulative doses of 5.16 and 7.74 mC/kg.
