Development of radiation dosage aggregation system in middle-range area

This study shows a system for radiation dosage aggregation by wireless communication. Environmental differences can have influence on the dosage in facilities like schools and factories. Especially in mountain forests, it could be more a significant difference, because fallen leaves would be piled in some areas easily but not in other areas. Therefore, it would be helpful if it were possible to measure the radiation dosage on several spots. It is troublesome to bring the equipment for measuring the radiation dosage to several spots observation, however. Therefore, a system, in which an equipment to measure the radiation dosage is its client and an equipment to aggregate the results of measured the radiation dosage is its server, has been developed. Because this system uses a module of 920[MHz] band between the server and the client, it is large enough to cover facilities such as elementary and junior high schools. In addition, its charging system by solar panels enables the operation for a long time. Moreover, the size of the server is small enough to carry and GPS information can be gotten so that the location of the client can be memorized to the server in installing the client.
