The genetically significant radiation dose is defined as the gonadal dose which, if received by every member of the population, would produce the same genetic hazard to the population as do the actual doses received by the individuals. PORETTI et al. published a value of 42.9 mrad for Switzerland as the result of X-ray diagnostic examinations in 1971. The contribution from nuclear medicine was determined with reference to special circumstances in the Canton of Basle City: the annual genetically significant dose amounted to 0.5 mrad in 1976. This value represents about 0.5% of the annual annual background radiation.
如果人群中的每一个成员都接受这一性腺剂量，那么它对人群产生的遗传危害将与个体实际接受的剂量所产生的危害相同。波雷蒂等人公布了瑞士在1971年X射线诊断检查的结果，其遗传显著辐射剂量值为42.9毫拉德。核医学的贡献是根据巴塞尔市州的特殊情况确定的：1976年的年度遗传显著剂量为0.5毫拉德。这个值约占年度天然本底辐射的0.5%。
