本文介绍了核工业放射性勘查计量站标准氡室(HD-1型),通过将原来只有一个探头的ZnS闪烁室式标准测氡仪改装成三探头的ZnS闪烁室式标准测氡仪和组装高灵敏度氡子体测量仪等措施,提高了仪器的灵敏度,降低了氡室量值的下限,并实现了环境评价中的氡子体测量,使核工业放射性勘查计量站标准氡室可靠给出氡子体的标准浓度变成现实。
This paper introduces the standard radon chamber (HD-1) of the nuclear industry radiological surveying station. By converting the original ZnS scintillation chamber standard radon detector with only one probe into a three-probe ZnS scintillation chamber standard radon detector and the assembly height Sensitivity of radon sonometry and other measures to improve the sensitivity of the instrument to reduce the lower limit of the radon chamber volume and realize the radon population measurement of environmental assessment so that the nuclear industry radon survey standard radon room reliably given radon The standard concentration of daughter becomes a reality.
