Three hours after irradiation in a dose of 800 R rats proved to be less resistant to following overheating (45 degrees C) than control animals. An increase of resistance to acute overheating was revealed at the end of 3 days after the irradiation. At the height of the radiation disease (the end of the 5th day) the period of occurrence of heat stroke and the duration of rat survival failed to di...
