Abstract

A new method was developed to determine the response ratio for converting the output current of 1.5 L inner-through type ionization chamber from that filled with P-10 gas to that filled with air, for the calibration of activity concentration of short-lived ⁴¹Ar. This method reduced both the time required for the procedure and the amount of sample needed compared to the conventional method. The response ratio was determined to be 0.680 ± 0.008 (k = 2), with an uncertainty within a practically acceptable range. Furthermore, the response ratio obtained using the new method was consistent within its uncertainty with the other two results, obtained by the conventional method and estimated using the result of a previous study.

评估充满空气的电离室与充满P-10气体的电离室对41Ar校准的响应比。

提出了一种测定1.5 L内透式电离室输出电流由充P-10气体转换为充空气的响应比的新方法，用于短寿命41Ar活度浓度的标定。与传统方法相比，该方法减少了程序所需的时间和所需的样品量。响应比为0.680±0.008 (k = 2)，不确定度在实际可接受范围内。此外，新方法得到的响应比在其不确定度内与传统方法得到的其他两个结果一致，这些结果是根据前人的研究结果估计的。

期刊介绍： Applied Radiation and Isotopes provides a high quality medium for the publication of substantial, original and scientific and technological papers on the development and peaceful application of nuclear, radiation and radionuclide techniques in chemistry, physics, biochemistry, biology, medicine, security, engineering and in the earth, planetary and environmental sciences, all including dosimetry. Nuclear techniques are defined in the broadest sense and both experimental and theoretical papers are welcome. They include the development and use of α- and β-particles, X-rays and γ-rays, neutrons and other nuclear particles and radiations from all sources, including radionuclides, synchrotron sources, cyclotrons and reactors and from the natural environment. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. Papers dealing with radiation processing, i.e., where radiation is used to bring about a biological, chemical or physical change in a material, should be directed to our sister journal Radiation Physics and Chemistry.
