A Novel Radiation Monitoring System

An ultra reliable radiation monitoring system is essential in order to provide safety to the workers in nuclear plants. The system should be able to detect minor fluctuations of the radiation field and activate an alarm when file radiation field exceeds predefined thresholds. The system implementation requires qualification for nuclear applications such as IEEE 323 and IEC 61503. In this paper such system is presented, it is a novel modular system that provides reliable monitoring of y radiation field. Although such systems were developed in the past, the presented system is based on modern electronics and 'went file extra mile' to provide a very high reliability achieved by using sophisticated methods of BIT (Built In Test) and feedback loops
