Doorway Monitoring System for Gamma Particle Detection

The system is developed to detect the radio-active sources like gamma particles. The doorway monitoring system consists two plastic scintillation detectors to detect the gamma source. The system would be designed in such a way that it detects the presence of humans with the help of IR sensor and will count the number of pulses through counters. The detector signal has to be processed for which suitable amplifier module has to be developed. The current status of the system would be transmitted to the remote PC application via Ethernet. The system has audio and visual indications to indicate the status of the system like Ready, Clean and System Fail. The user can set the alarm levels independently for the two detectors, the counting time using the touch display. The system has two modes of operation to meet user requirements. The system continuously acquires the counts and monitors the background radiation.
