Abstract
An irradiation environment for dosemeters calibration in the fluorescence X-ray field was set up at the Facility of Radiation Standards of the Japan Atomic Energy Agency by re-establishing the fluorescence X-ray calibration field that was established in 1989. The reference air kerma rates were determined using reference ionization chambers calibrated using X-ray narrow-spectrum series calibration field of the national metrology standard in Japan. Since no X-ray calibration field using fluorescence X-rays is available in Japan, the measurements were corrected by factors that accounts for differences in the fluorescence X-ray calibration field energy and the X-ray narrow-spectrum series calibration field energy. The conversion coefficients and correction factors for air densities for the fluorescence X-ray calibration field, including those unavailable in the ISO 4037 standard series, were derived from the measured X-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.
