Column type nuclear radiation dose detection system

Column type nuclear radiation dose detection systemIt is a device used for real-time monitoring of radioactive substances, which can monitor pedestrians or objects passing through detection channels online. It is widely used in airports, stations and other places.

• 
  

• System CompositionUsually composed of detectors, data processing units, alarm devices, and supporting structures. Most detectors use NaI (Tl) scintillation detectors, large volume plastic scintillation detectors, or He-3 proportional counting tube neutron detectors (optional). The data processing unit is responsible for analyzing the data collected by the detector, the alarm device emits an audible and visual alarm when the radiation dose exceeds the threshold, and the support structure is used to fix and support each component.

• Technical Specifications

• Detector sizeThe NaI (Tl) detector comes standard with a diameter of 50mm × 100mm, with a maximum diameter of 75mm × 100mm; the plastic flash detector comes standard with a diameter of 50mm × 100 × 1000mm.

• Energy resolutionThe NaI (Tl) detector has an energy resolution of no more than 8% for 137Cs (662KeV).

• Detection probabilityUnder certain conditions, the probability of gamma detection is ≥ 99.9%.

• Application fieldMainly used in important entrances and exits such as airports, docks, train stations, immigration security checkpoints, nuclear power plant control areas, nuclear waste treatment plants, government agencies, etc., for detecting radioactive substances carried by pedestrians and personal belongings.
