摘要

GD-L2型流气式固体氡源在对数字化气氡仪进行标定时采用常压下开放式采样,气压、气温等气候条件对标定K值准确度有一定影响。本文通过宁夏地震局近几年对全省4台SD-3A数字化气氡仪实地标定结果,对湖南南华大学氡实验室给出的气压、气温修正公式进行验证的同时还对标定技巧和注意事项做了阐述。
The K value is always affected by pressure and temperature in open sampling of digital gas radon instrument with GD-L2 flow-type solid seed.In this paper,based on the analysis of the calibration results of SD-3A digital gas radon instruments in Ningxia Earthquake Administration,we verify the modified formula of pressure and temperature given by Nanhua University Rn laboratory,and describe the skills and points of attention during calibrating.
