Classification of Radioactive Testing Instruments

According to the nature of the measurement object, it is mainly divided into:

α Measuring instrument:

β Measuring instrument:

γ Measuring instrument:

N measuring instrument:

Classified by monitoring purposes:

1. Entrance detectors: (for pedestrians, vehicles, trains, luggage, parcels, goods, containers, etc.) used for entry and exit inspection and quarantine as well as national security.

2. Venue (fixed point) dosimeter: used to detect abnormal emissions in the monitoring area, monitor and alarm the dose at the source site. 3. Patrol dosimeter: used for nuclear environment and safety, searching for radioactive sources, and discovering special nuclear materials. Personal dose alarm device: used for personal dose monitoring and alarm of personnel engaged in nuclear safety and nuclear counter-terrorism. Nuclide identification device: used to identify the types of radioactive isotopes and special nuclear materials and determine their intensity. It can be used in laboratories and portable.

4. Nuclear waste monitoring instrument: used for nuclear facilities, nuclear power plants, etc., to monitor and classify nuclear waste. Surface pollution monitoring instrument: equipped with monitoring of road surface (vehicle mounted), whole body and work clothes surface (fixed), desktop or any local surface of work area (portable).

5. Gas and aerosol measuring instrument: monitoring system for measuring the efflux of inert gases such as radon, thorium, and Xe, used in large nuclear facilities such as nuclear power plants

6. Nuclear imaging system: a large-scale nuclear instrument that uses a combination of radiation sources and sensors to scan and image monitoring targets

Other auxiliary facilities: such as automatic weather stations, aerosol sampling equipment, radio positioning systems, onboard equipment, etc.
