Effect of Environmental Temperature on the Response of Mice to Whole-Body Roentgen Radiation

Summary The net effect of a sufficiently cold environment is to lower the resistance of mice to the lethal action of X-rays. Subjection to a 10° or 30°C environment for 2 weeks prior to irradiation favors survival of irradiated mice maintained in those environments. Mice kept in a 30° environment that die following irradiation frequently show fatty changes in the liver.
