The US Navy, including the US Marine Corps and Naval Nuclear Propulsion Program (NNPP), has a robust radiological protection and monitoring program meeting (and typically exceeding, in the name of conservatism) federal law requirements. The program covers the variety of ways in which the Navy produces and uses ionizing radiation and radioactive sources: in medicine, nuclear ship propulsion and repair, industrial and aircraft radiography, and myriad other unique uses in carrying out its vital mission. In executing these programs, thousands of people across the world are employed as active-duty Sailors and Marines, government civilians, and government contractors. These workers include physicians, reactor operators, radiation safety officers, and nuclear repair workers, to name but a few. The health protection standards for these workers are promulgated in the publicly available Navy Medicine P-5055 Radiation Health Protection Manual (NAVMED P-5055), published February 2011 with Change 2 published December 2022, and are applicable to Navy and Marine Corps and NNPP radiation protection programs. The NAVMED P-5055 outlines the individual medical requirements for those qualified and able to receive exposure to ionizing radiation as part of their duties and requires that "Radiation workers receive focused medical examinations to establish whether or not cancer is present which would medically disqualify a person from receiving occupational radiation exposure." Additionally, without scientific or medical basis, the NAVMED P-5055 requires disqualifying those employees who have a history of cancer, cancer therapy, radiation therapy including radiopharmaceuticals received for therapeutic purposes, or bone marrow suppression from drawing dosimetry, entering radiation areas, or handling radioactive material. This policy, which exists regardless of lifetime occupational radiation dose or projected future radiation dose, applies to all cancers except adequately treated basal cell carcinoma. The policy is not supported by relevant scientific and medical literature; does not align with reasonable professional ethical standards; does not conform to US Navy radiological training, which stipulates the assumed increased risk of developing cancer from Navy and Marine Corps and NNPP occupational radiation exposure is small; and removes critical leadership and mentoring capability from the workforce unnecessarily. This article discusses in detail (1) this policy and its ramifications to the Navy and Marine Corps and NNPP workforce and (2) recommendations, benefits, and impacts for the Navy and Marine Corps and NNPP to remove this policy and still maintain a robust radiation protection program.
美国海军(包括美国海军陆战队和海军核动力推进计划 (NNPP))拥有健全的放射防护和监测计划,满足(通常以保守主义的名义超过)联邦法律要求。该计划涵盖了海军产生和使用电离辐射和放射性源的各种方式:在医学、核船舶推进和维修、工业和航空射线照相以及执行其重要任务的无数其他独特用途。在执行这些计划时,全球数以千计的人作为现役水手和海军陆战队员、政府文职人员和政府承包商受雇。这些工人包括医生、反应堆操作员、辐射安全官员和核维修工人等。这些工人的健康保护标准在公开的《海军医学 P-5055 辐射健康保护手册》(NAVMED P-5055)中公布,该手册于 2011 年 2 月发布,2022 年 12 月发布了第 2 次修订版,适用于海军和海军陆战队以及 NNPP 的辐射防护计划。NAVMED P-5055 概述了有资格并能够接受职业辐射照射的个人医疗要求,作为其职责的一部分,并要求“辐射工作人员接受重点体检,以确定是否存在癌症,这将使个人因接受职业辐射照射而丧失资格。”此外,没有科学或医学依据,NAVMED P-5055 要求取消曾患有癌症、癌症治疗、放射治疗(包括因治疗目的接受的放射性药物)或骨髓抑制的员工的资格,这些员工因进行剂量测定、进入辐射区域或处理放射性物质而受到限制。这项政策适用于除适当治疗的基底细胞癌外的所有癌症,无论其终生职业辐射剂量或预计未来辐射剂量如何,均适用于所有癌症。这项政策没有得到相关科学和医学文献的支持;不符合合理的专业道德标准;不符合美国海军的辐射培训,该培训规定,由于海军和海军陆战队以及 NNPP 的职业辐射暴露而导致癌症的假定风险较小;并且不必要地从劳动力中去除了关键的领导和指导能力。本文详细讨论了(1)该政策及其对海军和海军陆战队以及 NNPP 劳动力的影响,以及(2)为海军和海军陆战队以及 NNPP 取消该政策并仍保持健全的辐射防护计划而提出的建议、好处和影响。
