一、大剂量效应及线性假设许多人受大剂量照射的事件已出现多起,通过对这些人的研究,大剂量照射对健康的影响已相当清楚。其中某些资料总结于表1。日本原子弹袭击幸存者中,有24,000人平均受照射130雷姆,到1972年为止已多出现约120名癌症病例。15,000名英国人以 X 线治疗关节强直性脊椎炎,平均剂量370雷姆,约多发生 First, the high dose effects and linear Assumption Many people have been exposed to high doses of radiation events have occurred many times, through the study of these people, the impact of high doses of radiation has been quite clear. Some of the information is summarized in Table 1. Of the survivors of Japan’s atomic bombings, 24,000 were exposed to an average of 130 reims and by 1972 there were about 120 more cancer cases. 15,000 British X-ray treatment of ankylosing spondylitis, the average dose of 370 Rehm, occurs about
