Portable and vehicle-mounted sodium iodide (NaI) spectrometer

The vehicle-mounted detector can be used for continuous monitoring of environmental gamma air absorption dose rate, and can be equipped on nuclear radiation and anti-terrorism response and monitoring vehicles. It can identify the types of radionuclides emitted by nuclear and radiation pollution sources, and on this basis, single nuclide dose rate and energy spectrum analysis can be carried out.

Features:

1. Large volume detection of 4 ″× 4 ″× 16 ″NaI(Tl) square crystal with high sensitivity. Experiments show that the system can stably detect 16.5 mCi137-Cs unshielded bare source at a distance of 85 meters.

2, can quickly, real-time measurement of radioactive levels, rapid energy spectrum nuclide analysis.

3. Chinese interface software, simple operation, the system can realize automatic continuous measurement
