Abstract

KRISS developed a certified reference material (CRM) for measuring ²²⁶Ra, ²³²Th, and ⁴⁰K radioactivities in building materials to support successful compliance with regulatory guidelines aimed at maintaining indoor radon concentration levels at appropriate levels. Candidate materials (natural stones) were homogenized, characterized, and tested for homogeneity to international standards using gamma-ray spectrometry. The CRM will provide reliable quality assurance and quality control to testing laboratories that analyze natural radionuclides contained in building materials, thereby increasing the reliability of measurement results and ensuring that construction complies with national safety standards.

用建筑材料测量226Ra、232Th和40K放射性标准物质的研制。

KRISS开发了一种认证标准物质（CRM），用于测量建筑材料中的226Ra， 232Th和40K放射性，以支持成功遵守旨在将室内氡浓度维持在适当水平的监管指南。候选材料（天然石材）均质化，表征，并使用伽马射线能谱测试均匀性，以符合国际标准。CRM将为分析建筑材料中所含天然放射性核素的测试实验室提供可靠的质量保证和质量控制，从而提高测量结果的可靠性，并确保建筑符合国家安全标准。

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.
