A review of death certificates in New Hampshire, Maine, and Massachusetts for 1959-77 yielded a total of 1722 deaths among former workers at the Portsmouth Naval Shipyard where nuclear submarines are repaired and refuelled. Next of kin were contacted for 592. All deaths under age 80 were classified as being in former nuclear or non-nuclear workers depending on information supplied by next of kin. With U.S. age-specific proportional cancer mortality for White males as a standard, the observed/expected ratio of leukaemia deaths was 5.62 (6 observed, 1.1 expected) among the 146 former nuclear workers. For all cancer deaths, this ratio was 1.78. Among non-nuclear workers there was no statistically significant increase in proportional mortality from either leukaemia or from all cancers. The excess proportional leukaemia and cancer mortality among nuclear workers exceeds predictions based on previous data of radiation effects in man.
对新罕布什尔州、缅因州和马萨诸塞州1959年至1977年的死亡证明进行审查后发现，在朴茨茅斯海军造船厂（核潜艇在此进行维修和加油）工作过的前工人中，共有1722人死亡。已联系了592人的近亲。根据近亲提供的信息，所有80岁以下的死亡人员被归类为曾从事核工作或非核工作的人员。以美国白人男性特定年龄的癌症比例死亡率为标准，在146名前核工作者中，白血病死亡的观察/预期比率为5.62（观察到6例，预期1.1例）。对于所有癌症死亡，该比率为1.78。在非核工作者中，白血病或所有癌症的比例死亡率没有统计学上的显著增加。核工作者中白血病和癌症的比例死亡率过高，超出了基于此前人类辐射效应数据的预测。
