Radiation detection gate / for vehicles - DF-6501
The system, with a high sensitivity and a low false alarm rate, can further screen out radioactive material that is mixed with other materials. The whole system is easy to operatewith a small on-site maintenance workload, is has long-term stability under harsh working environments.Operating principle:
Radioactive elements in the decay process often produce a γ-ray.In case a person accesses the radiation monitoring system, it contains no radioactive material. The natural background radiation intensity received from the detector will fluctuate within a fixed range. Conversely, when the vehicle contains radioactive substances, γ-ray intensity exceeds the normal fluctuation range. A portal radiation monitoring system determines whether vehicle contains radioactive material by monitoring the changes in γ-ray intensity.
