| 摘 要： | 调研了各类钍射气(^220Rn)测量仪的刻度方法和存在的问题。针对各类^220Rn标准源的析出百分率常小于100％而有待准确测定这一关键问题，建立了流气闪烁室绝对测量方法，并用活性炭-γ谱法作了验证，解决了准确测定^220Rn标准源析出率的问题，为提高^220Rn测量仪刻度的准确性创造了条件。

| Abstract: | The calibration of various kinds of thoron monitor has been investigated. A main problem lies in that the emanation percentage of various kinds of thoron standard source is always less than 100%. In order to determine the emanation percentage accurately, an absolute measurement method with airflow-through scintillation cell was established, and its feasibility was verified by a comparative measurement with the activated charcoal-g spectrometer method. This will make the calibration accuracy of thoron monitors rising. |
