医療用線量標準九州地区センター(I)において校正された線量計のトレーサビリティ Traceability of the Ionization Chambers Calibrated at Kyushu Regional Center (I)
We investigated the traceability of the ionization chambers calibrated by the standard dosimeter with Kyushu regional center (I) for standard doses in medicine. Accuracy management of the ionization chambers of Kyushu regional center (I) has been maintained within 0.5% by intercomparison with that of the National Institute of Radiological Sciences (NIRS). The number of hospitals and the number of intercomparisons were 17 and 33 on an average per year, respectively. Accuracy of the ionization chambers of each hospital in recent years was less than 0.5% to the hospitals of 65-80% and less than 1.0% to those of 80-90%.
