一、高速中子对恶性肿瘤的治疗用高速中子束治疗恶性肿瘤是一种新的治疗方法,虽然使用时间不长,但已证明有效。在治疗中有时眼部不可避免地被照射,而引起放射性损害,但当疾病危及生命时,则此种治疗应认为可行。中子是原子核中不带电荷的粒子。在回旋加速器中,以氘核轰击铍靶即产生中子,而氘原子核的产生则是在回旋加速器中电场作用于氘气的结果。中子束自回旋加速器水平射出,以照射患 First, the treatment of high-speed neutrons on malignant tumors with high-speed neutron beam treatment of malignant tumors is a new treatment, although the use of time is not long, but has proved effective. Occasionally, during treatment, the eye is inevitably irradiated and causes radioactive damage. However, when the disease is life-threatening, such treatment should be considered viable. Neutrons are uncharged particles in the nucleus. In a cyclotron, bombardment of a beryllium target with deuterons produces neutrons, whereas generation of deuterium nuclei is the result of an electric field acting on deuterium in a cyclotron. Neutron beam self-cyclotron horizontal injection to irradiation affected
