The Korea Research Institute of Standards and Science (KRISS) has developed a primary system for the activity standardization of gaseous radon-222, based on the defined solid angle counting method. The size of adsorbed radon is determined by a Cyclone Storage Phosphor System, and a buffer chamber is introduced between the measurement chamber and the source for the purpose of gas purification. The measured activity of gaseous radon-222 and its associated measurement uncertainty obtained using the system are presented.
韩国标准科学研究院（KRISS）基于定义的立体角计数法，开发了一种用于气态氡-222活度标准化的初级系统。吸附氡的量由旋风存储磷光体系统测定，并且在测量室和源之间引入了一个缓冲室，用于气体净化。给出了使用该系统测得的气态氡-222的活度及其相关的测量不确定度。
