摘要: 为方便对部分测氡仪的自检校正,研制了一种体积小、成本低的校验氡箱。该氡箱体积20 L,采用铀矿粉作为氡源,其饱和氡浓度可达20.6 kBq/m3。通过理论计算和性能测试的结果表明,本校验氡箱成本低廉、制作简单、操作性强,且可通过理论计算得到氡浓度和氡照射量,非常适合对部分测氡仪进行自检校正,具有一定实用价值。

Abstract: To facilitate the self-correction to some radon meters, a small, low-cost radon box was developed. The volume of radon box with uranium as radon source is 20 L with an saturated concentration of radon up to 20.6 kBq/m3. Theoretical calculations and performance testing results show that the radon check box is feasible and cost efficient, with which radon concentration and radon exposure can be obtained simply through theoretical calculation. It is very suitable for self-correction of some radon measuring instruments.

Key words: radon, self-correction, calibration
