[Spontaneous motor activity and physical endurance of rats during acute radiation sickness developing against a background of the use of a radioprotective agent].

Cystamine given to rats prior to irradiation with a dose of 8 Gy (LD77/30) ameliorates significantly the severity of radiation sickness and restores spontaneous motor activity by the time of clinical recovery. However, movements that require physical efforts as well as physical endurance remain decreased.
