摘要

氡气（Rn-222）被世界卫生组织列为第一类致癌物，是导致非吸烟者患肺癌的主要原因。由于其在地壳中的自然起源，这种气体主要通过裂缝呼出运输，其浓度根据土壤形态和气候季节而变化。本文研究了氡气对boyacac Tunja市家庭健康的放射影响。为此，使用了固体核径迹探测器CR-39 (SSNTD)，暴露时间约为60天。结果显示，平均浓度为218.11 Bq·m-3，符合ICRP推荐的参考限值。这项研究强调了在哥伦比亚等发展中国家制定公共政策的重要性，这些国家还没有关于氡测量和控制的具体法规。获得的结果可用于确定风险区域，并作为实施预防措施和保护公众健康的基础。

Characterization of CR-39 detectors for monitoring indoor radon 222

Radon gas (Rn-222) is a carcinogenic agent classified by the WHO as Group 1 and is the leading cause of lung cancer in non-smokers. Due to its natural origin in the Earth's crust, this gas is primarily transported by exhalation through cracks, with concentrations that vary depending on soil morphology and climatic seasons. This article studies the radiological impact of radon gas on health in homes in the city of Tunja, Boyacá. For this purpose, solid-state nuclear track detectors CR-39 (SSNTD) were used, exposed for an approximate period of 60 days. The results showed average concentrations of 218.11

B q \cdot m^{- 3}

, a value that falls within the reference limits recommended by the ICRP. This study highlights the importance of establishing public policies in developing countries like Colombia, where specific regulations for radon measurement and control do not yet exist. The results obtained can be used to identify risk areas and serve as a basis for implementing prevention measures and protecting public health.

期刊介绍： Applied Radiation and Isotopes provides a high quality medium for the publication of substantial, original and scientific and technological papers on the development and peaceful application of nuclear, radiation and radionuclide techniques in chemistry, physics, biochemistry, biology, medicine, security, engineering and in the earth, planetary and environmental sciences, all including dosimetry. Nuclear techniques are defined in the broadest sense and both experimental and theoretical papers are welcome. They include the development and use of α- and β-particles, X-rays and γ-rays, neutrons and other nuclear particles and radiations from all sources, including radionuclides, synchrotron sources, cyclotrons and reactors and from the natural environment. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. Papers dealing with radiation processing, i.e., where radiation is used to bring about a biological, chemical or physical change in a material, should be directed to our sister journal Radiation Physics and Chemistry.
