Look for stated dose rate range and minimum detectable activity to ensure the unit can detect both low background changes and elevated levels

Display and readouts

Choose clear LCD or digital displays with dose-rate and cumulative dose readouts for quick situational awareness during emergencies

Portability and power

Prioritize compact, handheld units with common battery types or USB power options for easy inclusion in a grab-and-go kit

Durability and build

Select devices with robust housings and simple controls that perform reliably in field conditions and during extended monitoring
