External Dose Reconstruction of Radiation Exposure under Low Dose Rate in Long Term around Semipalatinsk Nuclear Weapon Test Site

本研究的目的是对前苏联塞米巴拉金斯克核武器试验场周围人群的外剂量重建进行讨论，并对核辐射下砖上的发光剂量测量和牙釉质上的电子自旋共振进行讨论。对于g=2.0018，50-70kJ/cm~2的太阳光剂量相当于1Gy的y剂量。我们了解日光照射对口腔内牙齿在辐射暴露后几十年的影响。除了过去的瞬时伽马射线照射外，口腔长期暴露的太阳光也是ESR剂量的一部分。牙齿上的ESR剂量有明显低于砖TLD剂量的趋势。Dolon村的TLD外照射剂量为0.71±4.14 Gy，而两名Dolon村居民(59岁和58岁)的ESR外照射剂量为0.1~0.2Gy.此外，…此外，据估计，他们在1949年第一次核爆炸中的年龄约为10岁。居民居住记录的确认是必要的。我们分析了2002年在当地调查中发现的地面核爆炸及其周围的长期核危害。直径30m的陨石坑表明这是一次0.1-0.3kt的核表面爆炸。这与1961年在俄罗斯原子能部和国防部报告的苏联实验年表上进行的实验相对应。地面核爆炸后的放射性尘埃是这些住宅区居民暴露于辐射的主要来源。我们认为，未来需要发展辐射防护计算机系统作为核心的防灾措施，这是一个国家核恐怖主义措施的防护基础指标方向的问题。为此目的，前苏联核武器试验场及其周围的研究工作应该是有用的。较少

The purpose of this study is external dose reconstruction for population around the former Soviet UnionSemipalatinsk Nuclear Weapon Test Site from discussion on thereto luminescence dosimetry on brick and electron spin resonance on tooth enamel exposed to nuclear radiation.The influence of the sun light revelation on enamel ESR dosimetry has been studied. For g □=2.0018, a dose of 50-70 kJ/cm2 for sun light is equivalent to a y dose of 1 Gy. We understand sun light irradiation influence of a tooth in the mouth for dozens of years afteryradiation exposure. In addition to past transient gamma ray radiation exposure, sun light exposure of a long term to a mouth is added as a part of ESR dose.There is a tendency that an ESR dose on a tooth is considerably lower than a brick TLD dose. External dose for Dolon village is estimated to be 0.71+_-4.14 Gy from TLD, on the other hand is estimated to be 0.l-0.2 Gy for two Dolon village inhabitants (59 years old and 58 years old) from ESR. In additi … More on, their age in the first nuclear explosion in 1949 is estimated to be about 10 years old. Confirmation of residential records of the inhabitants is necessary.We analyzed long-term nuclear hazards in and around surface nuclear explosion which we discovered bylocal investigation of 2002. The crater size of 30 m in diameter suggests a nuclear surface explosion with 0.1-0.3 kt output. This corresponds to experiments in 1961 on an experiment chronological table of the Soviet Union tunes that the Russian Atomic Energy Ministry and Department of Defense reported in 1996.Radioactive fallout after surface nuclear explosion is a main source of radiation exposure of these residence ward inhabitants. We think that development of radiation protection computer system as nucleus anti-disaster measures is demanded in future about a problem in a direction of a nation protection basis indicator of nuclear terrorism measures. Research work in and around the nuclear weapon test site of the former Soviet Union should be useful for this purpose. Less
