A Long Distance Monitoring Method for Strong Radiation Based on Wide Range Detection Technology

Aiming at the characteristics that the electronic components are easy damaged in strong radiation environment, a long distance detection method for strong radiation based on wide range detection technology is proposed. In this method, the GM counter is placed in the strong radiation environment, the measuring circuit is placed outside of the strong radiation environment, and a long cable is applied to connect the counter and the circuit. Theoretical analysis and experimental results show that it can improve the measuring range and service life of the counter, and can avoid the damage of circuit due to radiation. Therefore the method can be applied to the long distance monitoring in strong radiation environment.
