Frequently Asked Questions

AI
A Geiger counter is a specific type of radiation detector that measures the intensity of radiation in real-time. A dosimeter typically measures the cumulative dose of radiation absorbed over time, though many modern handheld devices combine both functionalities for comprehensive monitoring.
Entry-level devices can provide a general indication of radiation presence and relative levels, which is often sufficient for home safety checks. However, for precise quantitative data or professional compliance, investing in a mid-range or premium model with higher sensitivity and calibration is recommended.
Most consumer-grade detectors focus on beta, gamma, and X-rays, which are the most common concerns for general safety. If you are specifically concerned about alpha particles or neutron radiation, you need specialized equipment, as standard Geiger-Müller tubes often cannot detect these effectively.
