Abstract In order to overcome some deficiencies of passive radon track detectors such as long-term exposures required, novel polycarbonate track detector/activated-carbon-fabric (PCTD/ACF) multi-function radon badges are introduced for individual and environmental monitoring. Two twin-badge designs are provided; A-Type and B-Type each having one badge with polyethylene (PE) filter allowing 222Rn (3.82 d half-life) to pass while eliminating 220Rn (55.5 s half-life) and one badge with no PE filter for detecting 222Rn and 220Rn simultaneously. In A-Type twin badges, each badge has a PCTD half bare and half with ACF layer while in B-Type twin badges, each badge has a PCTD fully covered with ACF layer. The ACF adsorbs radon on its carbon active sites and exposes the PCTD underneath to alpha particles at a higher rate than that in PCTD with no ACF; thus having a track density ratio >1, called amplification factor (AF). Each badge type either single or twin can be independently used, depending on the application. The radon badges can be applied in practice with a constant AF value of ~1.5 for concentrations up to 2.52 ± 0.16 kBq.m−3 as studied for long-term radon individual and environmental monitoring. It is concluded that the monitors developed can be applied in practice for individual and environmental monitoring for the concentrations studied up to 2.52 ± 0.16 kBq.m−3. It should be noted that this concentration is not to be considered as the upper limit concentration beyond which is under further studies.

新型多功能聚碳酸酯/活性炭织物个人/环境氡双徽章

摘要 为了克服被动氡径探测器需要长期暴露等缺陷，引入了新型聚碳酸酯径迹探测器/活性炭织物（PCTD/ACF）多功能氡徽章用于个人和环境监测。提供两种双徽章设计；A 型和 B 型各有一个带有聚乙烯 (PE) 过滤器的徽章，允许 222Rn（3.82 天半衰期）通过，同时消除 220Rn（55.5 秒半衰期）和一个不带 PE 过滤器的徽章，用于检测 222Rn 和 220Rn同时地。在A型双徽章中，每个徽章都有一个半裸的PCTD，一半带有ACF层，而在B型双徽章中，每个徽章都有一个完全被ACF层覆盖的PCTD。ACF 在其碳活性位点上吸附氡，并以比没有 ACF 的PCTD 更高的速率将下面的PCTD 暴露于α 粒子；因此轨道密度比 >1，称为放大系数 (AF)。根据应用的不同，每种徽章类型可以单独使用，也可以单独使用。氡徽章可以在实践中应用，恒定 AF 值为 ~1.5，浓度高达 2.52 ± 0.16 kBq.m-3，如长期氡个体和环境监测所研究的那样。得出的结论是，开发的监测器可以在实践中应用于个人和环境监测，研究浓度高达 2.52 ± 0.16 kBq.m-3。应该注意的是，该浓度不应被认为是进一步研究中的上限浓度。氡徽章可以在实践中应用，恒定 AF 值为 ~1.5，浓度高达 2.52 ± 0.16 kBq.m-3，如长期氡个体和环境监测所研究的那样。得出的结论是，开发的监测器可以在实践中应用于个人和环境监测，研究浓度高达 2.52 ± 0.16 kBq.m-3。应该注意的是，该浓度不应被认为是进一步研究中的上限浓度。氡徽章可以在实践中应用，恒定 AF 值为 ~1.5，浓度高达 2.52 ± 0.16 kBq.m-3，如长期氡个体和环境监测所研究的那样。得出的结论是，开发的监测器可以在实践中应用于个人和环境监测，研究浓度高达 2.52 ± 0.16 kBq.m-3。应该注意的是，该浓度不应被认为是进一步研究中的上限浓度。
