摘要
日本原子能机构辐射标准设施建立了一个 241Am 伽马（γ）射线校准场，该场符合 ISO 4037 标准系列对γ射线参考场的要求。参考空气开尔玛率是使用一个参考电离室测量的，该电离室根据日本国家计量标准的 N-80 质量 X 射线校准场进行校准，并对校准场造成的光子能量差异进行了修正。241Am γ 射线校准场的转换系数，包括 ISO 4037 标准系列中未列出的转换系数，是根据测得的γ 射线通量率光谱计算得出的。
Establishment of a 241Am gamma calibration field based on international standards and its conversion coefficients.
A 241Am gamma (γ)-ray calibration field that meets the requirements for a γ-ray reference field as specified in the ISO 4037 standard series was established in the Facility of Radiation Standards of the Japan Atomic Energy Agency. The reference air kerma rates were measured using a reference ionization chamber calibrated by the N-80 quality X-ray calibration field of the national metrology standard in Japan and with a correction to account for differences in photon energy due to the calibration field. Conversion coefficients for the 241Am γ-ray calibration field, including those not listed in the ISO 4037 standard series, were calculated based on the measured γ-ray fluence rate spectra.
期刊介绍：
Radiation Protection Dosimetry covers all aspects of personal and environmental dosimetry and monitoring, for both ionising and non-ionising radiations. This includes biological aspects, physical concepts, biophysical dosimetry, external and internal personal dosimetry and monitoring, environmental and workplace monitoring, accident dosimetry, and dosimetry related to the protection of patients. Particular emphasis is placed on papers covering the fundamentals of dosimetry; units, radiation quantities and conversion factors. Papers covering archaeological dating are included only if the fundamental measurement method or technique, such as thermoluminescence, has direct application to personal dosimetry measurements. Papers covering the dosimetric aspects of radon or other naturally occurring radioactive materials and low level radiation are included. Animal experiments and ecological sample measurements are not included unless there is a significant relevant content reason.
