  • Electronic exposure dose meter and radiation handling operation management system employing the same
    Patent number: 6891476
    Abstract: An electronic exposure dose meter and a radiation handling operation management system is capable of realizing real time exposure management. The radiation handling operation management system has monitoring unit receiving an exposure dose amount measured by an electronic exposure dose meter having a radiation detector, its counter circuit and a PHS transmission and reception antenna, from a plurality of transmission and reception base station installed in a radiation handling operation site through bidirectional communication with a central management section via an external management base station, and deriving position of user of the electronic exposure dose meter for collecting and displaying position and exposure dose amount of the user. The electronic exposure dose meter has a radiation detector, a counter circuit, a PHS antenna for bidirectional communication with a central management section.
