[Effect of a highly dispersed iron powder on the longevity of irradiated mice]

In experiments on SHK mice it was shown that a single administration of highly-dispersed iron powder (0.2 to 100 mg/kg body weight) 20-30 min before irradiation with different doses exerted both a radioprotective and an enhancing effect and depended on both a radiation dose and a concentration of the iron powder administered.
