Frequently Asked Questions
Can a Geiger Counter detect all types of radiation?
Most Geiger counters detect beta, gamma, and X-ray radiation. However, detecting alpha particles usually requires a specialized pancake tube. Always check the specifications to confirm if alpha detection is included for your needs.
How accurate are these devices?
Accuracy depends on the sensor quality and calibration. Devices complying with standards like NIST offer better reliability. Regular calibration or factory verification ensures precise measurements over time.
Do these need internet to work?
Basic detection works offline. However, cloud logging and sharing features require internet. You can still log data locally without connecting to a network or server.
How long does the battery last?
Battery life varies by model and usage. Rechargeable units often last several days to weeks on standby. Frequent alarm use or bright screens may reduce this duration.
Can I use this at home?
Yes, many models are designed for home use. They help detect background radiation from building materials or natural sources. Ensure it suits your specific safety needs before purchase.
What is the unit of measurement?
Common units include μSv/h for dose rate and CPM for counts per minute. Some devices allow switching between units like μR/h. Check the manual for conversion details.
Are these waterproof?
Most devices are water-resistant but not fully waterproof. Avoid submerging them in water to protect internal electronics. Keep them dry during outdoor use to ensure safety.
Do they work on smartphones?
Some models offer Bluetooth connection to mobile apps. Dedicated apps provide visualization and maps. Not all devices support this, so check connectivity options carefully.
