| 摘 要： | 论述了水氡观测仪器在标定中应注意的问题,提出了在标定过程中,固体氡放射源与待标仪器的连接方式及吸源时间以多长为最佳的问题。报告建议为减少标准源的外在损失,提高K值的标定精度,在标定仪器时尽可能地采用图6的连接方式和严控或适当缩短吸源的时间。

| Abstract: | In this paper, the problems that should be noticed during calibrating the observation instrument of niton are discussed. Two problems, one is the connection mode between the solid niton radiation source and instrument that will be calibrated, and the other is how long time of inhaling niton source is the best, are worthy to discuss especially. In order to reduce the losing of standard source and improve the calibration precision of K value, we advises that the connection mode of figure 6 should be adopted in every possible way and the time of inhaling niton source should be strictly controlled or be shortened properly during calibrating the niton instrument. |
