How sensitive is it compared to traditional Geiger counters?

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.

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

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.

What's the battery life and charging time?

The device runs up to 200 hours on a single charge and recharges via USB-C in about 1.5 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.

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

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.

Can it detect contamination in food products?

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.

Spectrometrie gamma dans un format de poche

Vraiment parfait, pas de derive en temperature, la dose correspond. L'interface est tres bien, complete et simple. La taille du cristal etant seulement de 1cm3 la sensibilite aux hautes energies est tres faible mais on peut quand meme voir le potassium naturel a 1461keV et le 2614keV du thorium. Ca reste toutefois un appareil pour connaisseurs, vu son prix et sa complexite. A utiliser en complement d'un detecteur geiger qui permettra aussi de detecter les alpha et beta.

RadioCode

This unit has a resolution of 1keV and can be used with the software package: RadioCode available to download from the app store and run on your mobile. The app is free to use, and provides a very comprehensive range of setting along with the colour the colour graphics. I would suggest that you buy a case to protect the unit; I bought the distinctive hard yellow case which provide more than adequate protection for field use. You can test out your unit on an old smoke detector which uses a Am241 as its source. Peaks occur around 60keV (true: 59.6) and 26keV (true: 26.3,) the difference being due to the 1keV limitation per channel.

High quality device and easy to use.

Fabulous device, even for casual hobbyists! Was able to measure radiation levels and review gamma spectrometry on several items. These included a "healing bracelet" I purchased at a rock and mineral show, two fossils and a uranium glass pitcher I picked up at an antique store. The bracelet and fossils were far more radioactive than I would have thought, so it was very useful in how I decided to store and display these items. It took a little while to figure out the gamma spectrometer function, but the manuals and app are easy to download, and the Bluetooth ios app readily connects when using an iPhone 15. Great value and lots of fun!! 5 Stars!!!
