【摘要】 反照中子个人剂量计的体积小,使用方便,易于测量,越来越为人们所乐于采用。使用反照中子剂量计一般要用标定源进行标定。但是现场能谱的差异要影响现场测量值的精度,因此必须解决现场标定问题。本文介绍了现场标定的方法以及利用Bonner柱进行加速器现场的标定技术。更多还原

【Abstract】 Albedo neutron personnel dosimeter has been more and more widely used due toits small volume and easy in measurement. Great attention should be paid to the calib-ration technique which finally determines the error of the measurement. In fact, thereusually exists certain difference between the energy spectrum of the radioactive sourcefor calibration and that of the radiation field to be measured. In order to improve theaccuracy of the measurement, the problem of the in-field calibration technique shouldbe solved. In 9his paper, the method of the in-field calibration and the use of so-calledBonner cylinder for the in-field calibration of accelerator are described.更多还原
