Physical fitness of irradiated (20-200 Gy) mice and rats was estimated by the method of repeated swimming at a fixed distance. Revealed was the reduction adequacy of the two indices, that is the starting time and the fatigue coefficient, the latter being changed more considerably. The dose of 80-100 Gy determined the threshold of the cerebral damage and caused an irreversible decrease in the physical fitness of rodents. The role of exposure of the head in the impairment of the physical fitness of rats has been confirmed by the experiments with some body parts being shielded.
通过在固定距离下重复游泳的方法评估受辐照（20 - 200戈瑞）小鼠和大鼠的体能。发现两个指标的降低程度，即起始时间和疲劳系数，其中后者变化更为显著。80 - 100戈瑞的剂量确定了脑损伤阈值，并导致啮齿动物体能不可逆转地下降。通过对大鼠身体某些部位进行屏蔽的实验证实了头部暴露在大鼠体能损害中的作用。
