超致死剂量照射是近年来国际辐射损伤与防护研究中重要课题之一。中子弹作为弱冲击波、强辐射核武器,以爆炸时释放的强大的中子流作为主要杀伤因素,具有穿透力强、防护困难、人员吸收剂量大等特点。中子弹问世以来,超致死剂量辐射损伤与防治问题更为人们所重视。从未来战争的实际需要出发,我们选择了超致死剂量辐射损伤这一课题。 一般认为心脏辐射敏感性较低,只在大剂 Ultra-lethal dose irradiation is one of the most important topics in the international research on radiation damage and protection in recent years. As a weak shock wave and strong radiation nuclear weapon, the neutron bomb takes the strong neutron flux released by the explosion as the main killer. It has the characteristics of strong penetrating power, difficult protection and large dose absorbed by personnel. Since the advent of the neutron bomb, the radiation damage and prevention and treatment of sublethal dose have become more and more important. Starting from the actual needs of the future war, we have chosen the topic of sublethal radiation damage. Generally believed that the lower the sensitivity of cardiac radiation, only in large doses
