Abstract

The use of active personal dosimeters (APDs) is becoming more widespread in hospitals, generally found to be beneficial due to instant reading and useful for optimization purposes. In this study, three active personal dosimeters of Polimaster® model RadFlash® were chosen for characterization in terms of H_p(10) according to reference conditions of ISO 4037-3 (ISO, 2019b). The dosimeters were irradiated in X and gamma reference radiation defined in the ISO 4037-1 standard (ISO, 2019a), using the gamma irradiator and X-ray irradiator GE Isovolt 160, both located at the Dosimeter Calibration Laboratory (LCD) of the Center for Development of Nuclear Technology (CDTN). The repeatability of RadFlash® APDs resulted in a dosimeter percentage difference smaller than 5 %. The energy and angular response of each RadFlash® APD is within the interval from 0.71 to 1.67 for photon energies above or equal to 50 keV, considered adequate according to IEC 61526 standard (IEC, 2024).

以Hp（10）表示的X和γ辐射光束的有源个人剂量计的特性。

主动个人剂量计（apd）的使用在医院中越来越普遍，通常发现由于即时读取和用于优化目的而有益。在本研究中，根据ISO 4037-3 （ISO, 2019b）的参考条件，选择3台Polimaster®型号RadFlash®的有源个人剂量仪，以Hp（10）进行表征。使用位于核技术发展中心（CDTN）剂量计校准实验室（LCD）的伽马辐照器和X射线辐照器，对ISO 4037-1标准（ISO, 2019a）中定义的X和伽马参考辐射照射剂量计。RadFlash®apd的重复性导致剂量计百分比差异小于5%。每个RadFlash®APD的能量和角响应在0.71到1.67之间，光子能量高于或等于50 keV，根据IEC 61526标准（IEC, 2024）认为是足够的。

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.
