We have developed a personal radiation dosimeter “D-shuttle” in order to measure radiation dose in daily life after the accident of the Fukushima Dai-ichi Nuclear Power Plant. This dosimeter is small, lightweight, and can be used for more than one year without battery exchange. Furthermore, the user can check the total radiation dose and one day dose using a display module. In this article, we discuss history of the development, its specifications, and applications to real time monitoring.
