Exposure management system, dosimeter, and wireless relay device
First Claim
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, andmeans 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.

Abstract
An exposure management system includes dosimeters, wireless relay devices that wirelessly communicate with the dosimeters, and a monitoring device. The dosimeters are carried by workers for measuring exposure doses in a radiation management facility. The wireless relay devices transmit a monitor indication message that requests the dosimeters to provide respective responses that include information of measured exposure doses. The wireless relay devices receive the responses from the dosimeters by using allocated respective communication channels that are different from each other. Each dosimeter receives the monitoring indication message and generates a designated number of response times for providing a response to the monitor indication message, and determines a communication channel corresponding to each of the generated response times. The monitoring device is connected to the wireless relay devices for monitoring an exposure state of each of the workers through the wireless relay devices and dosimeters.

10. A dosimeter, which is carried by a worker for measuring an exposure dose in a radiation management facility and wirelessly communicates with a plurality of wireless relay devices by using respective communication channels allocated to the wireless relay devices, the allocated communication channels being selected from among a group of communication channels on a one-to-one basis, comprising:
-
means for receiving a monitor indication message transmitted by a relay device, the monitor indication message requesting the dosimeter to provide a response to a monitor indication message, said response including information of an amount of a measured exposure dose; means for generating a designated number of response times for providing said response, the 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, and determining a communication channel, selected from said group of communication channels, corresponding to each of the generated response times, the generated response times being later than a time that the 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. - View Dependent Claims (11, 12)
