This research reports the procedure in establishing the diagnostic beam qualities following IAEA TRS-457 for calibration in the field of diagnostic dose rate meters in the Office of Atoms for Peace (OAP), Thailand. Both methods, the IAEA TRS-457 and a novel method that was proposed in previous research, were adapted to achieve the RQR beam qualities at the laboratory. In this paper, the achievement of diagnostic beams is presented under the criteria within the technical protocol agreement. The correction factors of the primary standard and their uncertainties are reported. The calibration coefficients with uncertainties of the transfer chamber, A6 exradin, are proposed. These coefficients are compared with the calibration coefficients which were given by PTB that are shown acceptability. The uncertainty in the OAP calibration coefficients is estimated to be 1.20% at k = 2 for RQR and 1.21% at k = 2 for RQA. The laboratory is now able to provide calibration services and to be a national standard.

本研究报告了按照 IAEA TRS-457 建立诊断光束质量的程序，用于在泰国原子能促进和平办公室 (OAP) 的诊断剂量率计领域进行校准。IAEA TRS-457 和先前研究中提出的一种新方法这两种方法都适用于在实验室实现 RQR 光束质量。在本文中，诊断光束的实现是根据技术协议协议中的标准提出的。报告了主要标准的校正因子及其不确定度。提出了具有不确定性的转移室A6 exradin的校准系数。将这些系数与 PTB 给出的标定系数进行比较，显示可接受。 对于 RQR，k = 2，对于 RQA，k = 2 时为 1.21 % 。该实验室现已能够提供校准服务并成为国家标准。
