Portable radiation dosimeter

摘要

A microcontroller unit (3) measures and records a radiation exposure dose obtained from a detection output of a radiation detection unit (2), and when the radiation exposure dose or dose rate exceeds a predetermined threshold, issues a warning to the user by lighting or blinking a LED (4). The LED (4) is placed opposite a light-emitting/receiving element (62) of an electrical non-contact input device (6) provided on a display device (5), and is also used to transmit and receive recorded radiation dose data and a command or data transmitted from the non-contact input device (6). According to such a configuration, a portable radiation dosimeter that is compact and can manage the radiation exposure dose for a long term without placing a burden on the wearer can be realized.
