Published data indicate a partial or complete normalization period in hematopoiesis of animals exposed to chronic radiation injuries induced by 5 to 15 r of x radiation or by injections of Sr⁹⁰. However, in some cases acute sickness appears during the restoration period. Studies were made of 41 dogs; 17 dogs were exposed to x radiation and 24 dogs were given Sr⁹⁰ injections. Ten of the 17 exposed to x radiation received 10 r daily and the other seven received 5 r daily. Of the 10 receiving 10 r, three dogs did not exhibit any normalization period. The remaining seven receiving 10 r and the seven receiving 5 r exhibited a definite restoration of the hematopoietic function after 35 to 50 weeks (total doses of 2000 and 1200 r, for the respective groups). Single intravenous injections of 0.1 to 0.2 mc/kg of Sr⁹⁰ resulted in acute radiation sickness with 20% fatality after 1 to 2 months. In the remaining 80%, peripheral blood erythrocytes were restored to the initial number 5 months following the injection. Twenty to thirty-five months later, the erythrocyte number exceeded the initial number by 30 to 40%.
