COMPARISON OF PERSONAL DOSE EQUIVALENT Hp(10) IN 137CS RADIATION BETWEEN THE PRIMARY STANDARDS LABORATORIES OF JAPAN AND AUSTRALIA USING BeO OSL PERSONAL DOSEMETERS

Abstract

A comparison of personal dose equivalent Hp(10) for 137Cs radiation was conducted between the primary standards laboratories of Japan and Australia. A set of 120 commercially available passive BeO OSL dosemeters were used (Dosimetrics GmbH, Munich). The aim was to investigate the precision which could be obtained with this technique, and to confirm the personal dose equivalent delivery methods in each standards laboratory. A dose of 5 mSv was delivered to 40 dosemeters in each country, and 40 dosemeters were used as controls. The result of the comparison was a ratio of Hp(10) in Japan to Australia of 1.006 with a combined standard uncertainty of 3.2%. The statistical uncertainty was 0.32% indicating that passive dosemeters can be used for comparisons of high precision.

BATAN PERSONAL DOSE EQUIVALENT Hp (10) AND Hp (3) INTERCOMPARISON RESULTS AT 2018 & 2019

“…In addition to being used for the long term, TLD also has several advantages compared to film dosimeters, such as higher sensitivity, dose reading resolution <1 mGy, and not influenced by the level of high humidity and magnetic field. Besides TLD, optically stimulated luminescence (OSL) dosimeters can also be used as individual dosimeters (Butler et al, 2018;Jumpeno et al, 2017;Kurasawa et al, 2017).…”
