Abstract:
An environmental gamma radiation monitoring system via mobile telephone network was developed using gamma radiation measurement system, microcomputer, and mobile telephone. This system consisted of 2 parts: sub and central environmental gamma radiation monitoring station. The sub-station measured, analysed and reported gamma radiation level and also alarmed when level exceeded the safety limit. The central station is the center unit for reporting all measured data and alarmed when the data received from sub-station in form of short message exceeded the limit. Results of performance testing showed that the developed system had a capability of reporting the measured gamma radiation level, alarming when level exceed the limit and collecting all data onto microcomputer conveniently and correctly. This application technique possed the low cost mobile telephone as a device to transfer data economically.
