The selection of multifunctional radiation monitoring devices should revolve aroundMeasurement requirements, core performance, usage scenarios, complianceThe four core dimensions are comprehensively judged based on details such as radiation type, accuracy requirements, and operational convenience, to avoid blindly pursuing "multifunctionality" and neglecting core practicality. The following mainly introduces the core content:

1. Radiation type adaptation

• Daily environment/nuclear medicine/radiotherapy department: focus on measuring gamma/X-rays (most commonly);

• Nuclear industry/radioactive waste treatment: It is necessary to cover multiple types of alpha, beta, and gamma (to avoid missing surface contamination);

• Reactor/Neutron Experiment: Additional support is required for neutron radiation measurement (specialized detector);

• Common monitoring types: ionizing radiation (alpha, beta, gamma, X-rays), neutron radiation (special scenarios), need to be confirmed according to the usage scenario:

2. Measurement scenario and range

• Daily environmental monitoring (background radiation): low range (such as 0.01 μ Sv/h~100mSv/h), requiring high sensitivity;

• Industrial flaw detection/radiotherapy equipment: large range (such as 1 μ Sv/h~10Sv/h), requiring anti saturation and fast response;

• Surface pollution monitoring: It is necessary to support activity units (such as Bq/cm ²) rather than just dose rates (μ Sv/h).

• Range matching: A narrow range can cause overflow (unable to read), while a wide range can affect low-dose accuracy
