Radiation-monitoring system by means of signal transmission with optical fiber

There exist various sizes of radiation-monitoring systems ranging from a small system consisting of a few detectors to a large one consisting of several hundred detectors. The recent development of personal computers has improved their reliability and also has realized a large size of memory. This circumstance has increased demand for small radiation-control systems where computers are on-logging of detected radiation. On the other hand, it is necessary to improve the reliability and to simplify the maintenance process for large systems, because they are composed of many elements. We describe new radiation-monitoring systems based on the optical signal transmission, which can apply to the various recent needs. (author)
