Probable risks for the occurrence of somatic effects due to diagnostic radiology and nuclear medicine are summarised. The biological background of radiation carcinogenesis and epidemiological results are discussed. At the Leiden University Medical Centre the average effective dose per examination due to diagnostic radiology and nuclear medicine amount to 0.95 and 4.4 mSv, respectively. These values correspond well with the average values of 0.82 and 3.0 mSv reported for The Netherlands as a whole. Since radiological examinations are performed at a much larger frequency than nuclear medicine the relative collective dose for the first type of examinations is higher than the latter. Risk for occurency of malignancies are at least one order of magnitude lower than the hypothetical risk due to the background radiation typical of The Netherlands.
总结了诊断放射学和核医学导致躯体效应发生的可能风险。讨论了辐射致癌的生物学背景和流行病学结果。在莱顿大学医学中心，诊断放射学和核医学每次检查的平均有效剂量分别为0.95和4.4毫希沃特。这些值与整个荷兰报告的0.82和3.0毫希沃特的平均值非常吻合。由于放射学检查的执行频率比核医学高得多，因此第一种检查类型的相对集体剂量高于后者。恶性肿瘤发生的风险至少比荷兰典型背景辐射导致的假设风险低一个数量级。
