Various radiation detectors including electronic personal emergency radiation detectors (PERDs), radiochromic film cards and thermoluminescent dosimeters (TLDs) were used to validate a subset of the radiological test requirements listed in the American National Standards Institute/The Institute of Electrical and Electronic Engineers (ANSI/IEEE) N42.49 standard. The subset of tests included the following: comparing the readout of the detectors with the value given at the National Institute of Standards and Technology (NIST); testing of the alarm settings (when applicable) in air-kerma (or exposure) and air-kerma rate (or exposure rate) mode; and investigating the effect of testing the detectors mounted on a phantom and free in air. The purpose of this work was not to test the performance of the sample of detectors used. Instead, the detectors were used to validate the requirements of the written standard being developed. For this purpose, the performance and response of these instruments were recorded when placed in (137)Cs, and x-ray beams at different air-kerma rates and test conditions. The measurements described in this report were performed at the NIST x-ray and gamma-ray radiation calibration facilities. The data in this report provide a benchmark in support of the development of the ANSI/IEEE N42.49 standard.
各种辐射探测器，包括电子个人应急辐射探测器 (PERD)、光致变色胶片卡和热释光剂量计 (TLD)，被用于验证美国国家标准协会/电气和电子工程师协会 (ANSI/IEEE) N42.49 标准中列出的部分放射测试要求。测试子集包括以下内容：将探测器的读数与国家标准与技术研究所 (NIST) 给出的值进行比较；在空气比释动能 (或照射量) 和空气比释动能率 (或照射率) 模式下测试报警设置（如适用）；以及研究在探测器安装在模体上和自由空气中时的测试效果。这项工作的目的不是测试所使用的探测器样本的性能。相反，探测器被用于验证正在制定的书面标准的要求。为此，当这些仪器放置在 (137)Cs 和不同空气比释动能率和测试条件的 X 射线束中时，记录了这些仪器的性能和响应。本报告中描述的测量是在 NIST X 射线和伽马射线辐射校准设施中进行的。本报告中的数据为支持 ANSI/IEEE N42.49 标准的制定提供了基准。
