The National Council on Radiation Protection and Measurements (NCRP) believes that the most critical need for the nation in radiation protection is to train, engage, and retain radiation professionals for the future. Not only is the pipeline shrinking, but for some areas there is no longer a pipe! When the call comes to respond, there may be no one to answer the phone! The NCRP "Where are the Radiation Professionals?" initiative, Council Committee (CC) 2, and this year's annual meeting are to focus our efforts to find solutions and not just reiterate the problems. Our next major initiative is CC 1, where the NCRP is making recommendations for the United States on all things dealing with radiation protection. Our last publication was NCRP Report No. 116, Limitation of Exposure to Ionizing Radiation, in 1993-time for an update. NCRP has seven active Program Area Committees on biology and epidemiology, operational concerns, emergency response and preparedness, medicine, environmental issues and waste management, dosimetry, and communications. A major scientific research initiative is the Million Person Study of Low Dose Radiation Health Effects. It includes workers from the Manhattan Project, nuclear weapons test participants (atomic veterans), industrial radiographers, and early medical workers such as radiologists and technologists. This research will answer the one major gap in radiation risk evaluation: what are the health effects when the exposure occurs gradually over time? Other cutting edge initiatives include a re-evaluation of science behind recommendations for lens of the eye dose limits, recommendations for emergency responders on dosimetry after a major radiological incident, guidance to the National Aeronautics and Space Administration with regard to possible central nervous system effects from galactic cosmic rays (the high energy, high mass particles bounding through space), re-evaluating the population exposure to medical radiation (NCRP Report No. 160, Ionizing Radiation Exposure of the Population of the United States, is over 10 y old, and computed tomography exams have increased substantially since then), and concerning whether the linear no-, threshold model is still the best available for purposes of radiation protection (not for risk assessment). We believe evaluation of heart disease and cerebral vascular disease following low-dose and dose-rate exposure is important for assessments of possible detriment from such exposures. We continue to seek the necessary resources to follow our quest to improve radiation protection for the public!
美国国家辐射防护与测量委员会(NCRP)认为,国家在辐射防护方面最迫切的需求是为未来培养、吸引并留住辐射专业人员。不仅人才储备在减少,而且在某些领域甚至已经没有人才输送渠道了!当需要做出响应时,可能无人接听电话!NCRP的“辐射专业人员都在哪里?”倡议、理事会委员会(CC)2以及今年的年会旨在集中精力寻找解决方案,而不仅仅是重申问题。我们的下一项主要倡议是CC 1,NCRP将在其中就所有与辐射防护相关的事宜向美国提出建议。我们上一份出版物是1993年的NCRP第116号报告《电离辐射照射的限制》,现在是时候进行更新了。NCRP有七个活跃的项目领域委员会,分别涉及生物学与流行病学、操作问题、应急响应与准备、医学、环境问题与废物管理、剂量测定以及通信。一项重大的科学研究倡议是百万人大剂量低剂量辐射健康效应研究。该研究涵盖了曼哈顿计划的工作人员、核武器试验参与者(原子老兵)、工业放射技师以及早期的医务工作者,如放射科医生和技术人员。这项研究将填补辐射风险评估中的一个主要空白:当暴露随着时间逐渐发生时,对健康有哪些影响?其他前沿倡议包括重新评估眼睛晶状体剂量限值建议背后的科学依据、针对重大放射性事件后应急响应人员的剂量测定建议、就银河宇宙射线(穿越太空的高能、高质量粒子)可能对中枢神经系统产生的影响向美国国家航空航天局提供指导、重新评估公众的医疗辐射暴露情况(NCRP第160号报告《美国人口的电离辐射照射》已有十多年历史,自那时起计算机断层扫描检查大幅增加),以及探讨线性无阈模型是否仍然是辐射防护(而非风险评估)的最佳可用模型。我们认为,评估低剂量和低剂量率照射后的心脏病和脑血管疾病对于评估此类照射可能造成的损害非常重要。我们将继续寻求必要资源,以推进我们改善公众辐射防护的探索!
