Smart Geiger Counter Radiacode-102 with Free Mobile App. Nuclear Radiation Detector

The Radiacode 102 stands as a remarkable achievement in engineering, showcasing state-of-the-art electronics and software clearly designed by a small team of passionate experts. Their dedication to creating the best possible product within budget constraints is evident, as is their enthusiasm, reflected in their active engagement with users on forums like Geigerzählerforum. This advanced yet user-friendly device revolutionizes the consumer market for radiation detection, making gamma spectroscopy accessible to a broad audience, including young physics enthusiasts. Its combination of affordability, performance, portability, and ease of use opens up fascinating opportunities to explore radioactivity using common sources such as thoriated gas lamp mantles, thoriated welding rods, uranium glass, and radioactive minerals like thorite and uraninite. The Radiacode 102 serves practical purposes too, quickly alerting users to increased gamma radiation levels during potential nuclear incidents, and capable of measuring weak radioactive contamination in environmental samples, though this requires extended measurement periods and lead shielding. As a scintillator detector, it not only measures radioactive radiation with high sensitivity but also identifies its origin, boasting approximately 7 times more sensitivity for gamma radiation than the Mazur PRM 9000 pancake Geiger counter and 20 times more than the GammaScout. However, it's less sensitive than Geiger counters for beta and especially alpha radiation detection. The device comes with versatile software options, including mobile apps for Android and iPhone, a Windows application (currently limited to USB connectivity), and compatibility with third-party software like BecqMoni for easy Bluetooth connectivity. It can also function independently, storing data in internal memory. In terms of performance, my unit achieves 9.8% resolution for Cs-137, sufficient for isotope identification, though it can't match the sensitivity and resolution of larger, more expensive scintillators. For highly sensitive measurements, such as detecting Cs-137 in food, I employ a NaI(Tl) detector with 50 times larger crystal from GammaSpectacular and a lead shield to suppress the background radiation. Overall, the Radiacode 102 represents a significant advancement in consumer-grade radiation detection technology, proving invaluable for both amateur enthusiasts and professionals in the field of radiation detection and analysis. I attach some spectra measured with the Radiacode-102 and the Android app: Radium 226, Thorium 232, Lutetium 176, Potassium 40, Cesium 137, Cobalt 60, Americium 241 and the beta emitter Strontium 90.

This is an interesting device. I've had a bit of time to tinker with it and have taken it out in the field. It's not a geiger counter. A geiger counter uses a geiger-mueller tube. A typical thin-walled geiger tube can only really register beta and pick up that there is radiation present, not its energy. It's basically numbers of clicks of ionizing radiation without being able to tell you anything about it. This is a scintillator that mostly picks up gamma and tracks voltage of counts in kev. It tracks these counts in spectra, spectrograms over time, and location. It's not quite a lab-grade device, but it puts this sort of monitoring and tracking into an affordable device. It's the kind of device you can carry with you and track radiation levels and doses around your location. You can put it next to an emitter, take a spectrum and identify the type of emitter. If you have an alpha or beta source, like uranium or thorium, it doesn't necessarily read it directly, but records the gamma emissions of decay chain products to identify the source. It's very sensitive to these types of sources in a way that a cheaper geiger tube device usually isn't. I think that the intended "killer ap" would be using it to monitor food sources down wind of Chernobyl. It's a European product in that way. That's not as much of a concern for me. For me, it can be a bit of a toy where I can take spectra of common emitters, like uranium glass, vintage dishes, lantern mantles. I've figured out that my downtown areas is slightly more radioactive than where I live. However, it's not a toy. It's a pretty serious device. There's a feature in the app that lets you identify emitter types through the differing peaks on a spectrum. You can take a baseline background reading and subtract it from your spectra to really make the source type more clear. It really does do a lot for the money. I use it as a safety device when I replace smoke detectors for people. I can check them for radiation emitters before disposing of them so i don't expose myself and others. As well, I run a desert education group and it helps in identifying minerals in the field. I found out one of my camera lenses is a beta emitter (thorium glass) which doesn't change much, but I'm happy that I know not to carry it in my vest pocket for 12 hours a day. My heads up is that the Android app is much more mature than the iOS app. The iPhone app is missing a lot of features, but it seems like they are updating about once a month. As of February 2024, the tracks feature works and the radiation level and dose rate features are working. You can take spectra but can't save them yet. I hope this gets fixed quickly, since this is maybe the best feature for me. The android app has pretty modest requirements, so I borrowed an old Android phone to save spectra and do background subtraction until these features are added. I don't think this is a deal killer. Also, the Android app has some odd English locutions so it might take some time to figure out what these features are, and you might need to refer to the documentation a few times before getting comfortable. So far, the iOS app is much more intuitive, though it is a work in progress.

Following a minor issue with the item, the seller demonstrated exemplary commitment to resolving it with the level of professionalism and rigor one expects from a product of such inherent quality. The replacement unit was delivered in pristine condition, and the reverse logistics were handled with precision—using reusable packaging, clear documentation, and timely coordination. Communication remained consistently courteous, efficient, and solution-driven throughout. This experience reflects a supplier with operational maturity, technical accountability, and a genuine focus on customer assurance. Highly recommended for those who value excellence not only in instrumentation, but in the integrity of the service behind it.
