24. 最近就辐射照射对癌症以外疾病的影响进行审查的是委员会 1982 年和 1993年的报告，审查表明存在着一个最低剂量，即阈剂量，临床上尚未发现低于这个剂量所产生的辐射影响。虽然阈剂量的数值很难确定，并且该剂量可能随着人体组织和测量技术而变化，但原子弹爆炸幸存者数据表明，辐射照射与癌症以外疾病发生率之间的关联可以发生在迄今为止被认为是产生各种所谓的决定性影响的阈值以下的各种剂量水平。
24. Effects of exposure to radiation on conditions other than cancer were most recently reviewed in the Committee’s 1982 and 1993 reports, showing the presence of a minimum dose—a threshold dose—below which no radiation effects are detected clinically. Although a value for the threshold dose is difficult to define and may vary according to tissues and measuring techniques, the atomic bombing survivor data show that associations between radiation exposure and the incidence of diseases other than cancer can occur at levels of dose below those hitherto considered as thresholds for various so-called deterministic effects.
