Drastic changes in the level of catecholamines (dophamine and noradrenaline) in the central regulatory area of the sympathetic-adrenal system-hypothalamus--caused by continuous gamma irradiation of rats were observed. The irradiation was performed with the doses of 9 to 165 cGy at a rate of 1.1 cGy/day and with the doses of 17 to 315 cGy at a rate of 2.1 cGy/day. Dose dependences of the effect were of a non-monotonic nature. Conclusion was made of a high sensitivity of the sympathetic-adrenal system to the action of chronic low-dose gamma irradiation.
观察到，由于对大鼠进行持续的γ射线照射，导致交感-肾上腺系统的中枢调节区域——下丘脑内的儿茶酚胺（多巴胺和去甲肾上腺素）水平发生了剧烈变化。照射剂量为9至165厘戈瑞，照射速率为每天1.1厘戈瑞；以及剂量为17至315厘戈瑞，照射速率为每天2.1厘戈瑞。该效应的剂量依赖性呈非单调性质。得出的结论是，交感-肾上腺系统对慢性低剂量γ射线照射的作用具有高度敏感性。
