Question 1

How sensitive is it compared to traditional Geiger counters?

Accepted Answer

Radiacode uses a scintillation crystal and semiconductor photomultiplier to measure 300–500 CPM under natural background—about 15–20× higher than typical Geiger counters. This higher sensitivity reduces the chance of missing hotspots.

Question 2

Can it recognize specific isotopes like Cesium-137, Radium-226, Uranium-238, or Thorium-232?

Accepted Answer

Yes, and many more. Unlike traditional Geiger counters, Radiacode can help identify radiation sources by analyzing energy levels. Many isotopes have unique characteristic energy patterns, allowing detection of specific isotopes via the mobile app.

Question 3

What's the battery life and charging time?

Accepted Answer

The device runs up to 200 hours on a single charge and recharges via USB-C in about 2 hours. This long battery life makes it easy to carry daily in a pocket or bag, while its fast response helps you stay aware of radiation levels.

Question 4

Does it work with both Android and iPhone? Does it work without internet/WiFi connection?

Accepted Answer

Yes. The device has powerful and fully free apps for iOS, Android, macOS, and Windows. All apps work offline and do not require an internet connection during use. It connects via Bluetooth to iOS, Android, and macOS, and via USB cable to Windows.

Question 5

Can it detect contamination in food products?

Accepted Answer

Yes. The iOS and Android apps include a special mode for estimating Cesium-137 in food using a Marinelli beaker (sold separately). This lab-based method is far more accurate than typical Geiger counters, which often can't detect food contamination.
