在地下粒子物理实验中，铀系衰变链产生的放射性稀有气体Rn可能是一个严重的本底源。我们一直在开发高灵敏度的氡探测器，用于在神冈地下实验室分析氡。为了达到更低的本底水平，我们研制了一种密封性更好的新型氡气探测器。通过我们的校准系统得到了检测效率的高压依赖关系和湿度依赖关系。还测量了新的测氡仪的本底水平。
In underground particle physics experiments, the radioactive noble gasRn generated from the decay chain of the uranium series could be a serious background source. We have been developing high-sensitivity radon detectors to assay radon in the Kamioka underground laboratory. In order to achieve a further low background level, we developed a new radon detector with better hermeticity. The high-voltage dependence and humidity dependence of the detection efficiencies were obtained through our calibration systems. The background level of the new radon detector was also measured.
