KURAMA-micro, a personal dosimetry system with network and positioning capability, is developed for such purpose. KURAMA-micro consists of a semiconductor dosimeter and a DAQ board based on OpenATOMS. Each unit records radiation data tagged with their measurement time and locations, and uploads the data to the server over a ZigBee-based network once each unit comes near one of the access points prepared expected activities range of users. Location data are basically obtained by a GPS unit, and an additional radio beacon scheme using ZigBee broadcast protocol is also used for the indoor positioning. The development of a proto-type KURAMA-micro is finished and a field test for the workers of a nuclear reactor under normal operation is planned in the spring of 2015.
