1. An exposure management system comprising:
a plurality of dosimeters, which are carried by workers for measuring exposure doses in a radiation management facility, each dosimeter comprising: means for receiving a monitor indication message transmitted by a relay device, the monitor indication message requesting said each dosimeter to provide a response to the monitor indication message, said response including an amount of a measured exposure dose, means for generating a designated number of response times based at least on a number of response time slots indicated in the monitor indication message transmitted by the relay device, a response time of the designated number of response times corresponding to a time at which a response is to be transmitted, for providing said response and determining a communication channel, selected from a group of communication channels, corresponding to each of the generated response times, the generated response times being later than a time that reception of the monitor indication message ends, and means for transmitting said response at each of the generated response times by using the determined communication channel corresponding to said each of the generated response times; a plurality of wireless relay devices that wirelessly communicate with the dosimeters and are allocated with respective communication channels that are different from each other, the allocated communication channels being selected from among the communication channels of said group on a one-to-one basis, the wireless relay devices being configured to transmit the monitor indication message to the allocated communication channels and receive from the dosimeters respective responses to the monitor indication message; and a monitoring device connected to the wireless relay devices, for monitoring an exposure state of each of the workers through the wireless relay devices and dosimeters. |
