Radon, a radioactive inert gas that comes from the decay of naturally occurring radioactive species, poses a substantial health risk due to its involvement in lung cancer carcinogenesis. This work proposes a metrological approach for determining radon exhalation rates from diverse building materials. This methodology employs an electrostatic collection chamber for alpha spectrometry of radon isotopic decay products. Experimental evaluations were conducted particularly focusing on volcanic gray tuff from Sant'Agata de' Goti (Campania region, Italy), a material commonly utilized in construction, to assess radon exhalation rates. The study aligns with Legislative Decree 101/2020, a transposition of European Directive 59/2013/Euratom, highlighting the need to identify materials with a high risk of radon exhalation. Moreover, this work supports the goals of the Italian National Radon Action Plan related to the aforementioned decree, aiming to develop methodologies for estimating radon exhalation rates from building materials and improving radioprotection practices.
氡是一种由天然存在的放射性物质衰变产生的放射性惰性气体，由于其与肺癌致癌作用有关，会带来重大健康风险。这项工作提出了一种计量方法，用于测定各种建筑材料的氡析出率。该方法采用静电收集室对氡同位素衰变产物进行α能谱分析。特别针对意大利坎帕尼亚地区圣阿加塔-德戈蒂的火山灰质凝灰岩（一种常用于建筑的材料）进行了实验评估，以评估氡析出率。该研究符合第101/2020号立法令，该法令是对欧洲指令59/2013/Euratom的转化，强调了识别具有高氡析出风险材料的必要性。此外，这项工作支持意大利国家氡行动计划与上述法令相关的目标，旨在开发估算建筑材料氡析出率的方法并改进辐射防护措施。
