Calibration of Therapy-level Dosimeters in Japan by Association for Nuclear Technology in Medicine (ANTM)

In 2004, the calibration system of therapy-level dosimeter sensitivity has been reformed in Japan. An organization of new dosimeter calibration system by Association for Nuclear Technology in Medicine (ANTM) was launched from April, 2004 instead of the old system which was operated by Japan Radiological Society (JRS). Since then, about 5 years have passed, and the calibration work has been carried out favorably in general. It is thought that the transfer of dosimeter calibration system was performed smoothly.
