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

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.

This is a truly amazing, sleek-looking device -- more than just a "dumb" Geiger Counter which basically just lets you know whether ionizing radiation was detected, this opens up a whole new way of looking at sources of natural (and artificial) radiation around you by giving you information about the "strength" of the radiation detected and provides a graph of the different energies of radiation detected which allows you to identify the actual source of the radiation since each element and source has its own characteristic footprint. This is a tiny device which is an amazing value for the money given what it enables you to do. A must have for a physics geek and amazing gift for the nerd who thought they had everything but will quickly fall in love with this device. There are a ton of instructional videos and information on their web site which makes for a low barrier of entry for this highly capable device.

Part of my EDC now. I make sure it always has a charge, the battery life is great, even with frequent checking and backlight illumination I am constantly 7+ days on a charge. I wear it at work everyday around cabinet xray machines, yes I know it does so much more, and I do use it for other things but this is my daily use. It is interesting to me to see my exposure and watch the peaks as the lead curtains sway. Durability is amazing, I did get the silicone case to put it on, which makes it easier to hand of my badge or off my belt. I can be rough with things in the work place (broken phone screens, watch screens, broken pens) and I have not had any damage to this at all, not even a scratch on the screen and this is several months of ownership. Functionally this is amazing and keeps getting better. The recent update even allowed testing food for radiation on Iphone which was previously only for the higher end monitors. This does seem to scare some people that know little of radiation safety princables, some that I know after showing the geiger clicks around smoke detectors talked about throwing them all out and taking the risk. Be prepared if purchasing to have to explain more about readiation than you ever thought you would need to do. As a side note no need to send this through TSA baggage screening to be nosey, it maxes out the sensor. You may also find yourself looking to buy things just to play with it (Amaon does sell uranium ore, and thorium welding rods)

Unfortunately I didn't get the unit because the Amazon driver left the package outside and I didn't get a refund or replacement. However, I have been using a borrowed unit and it is a wonderful item to have if you are a rock hound enthusiast. The great thing is that it allows not only to detect hot rocks, but the built in spesctroscopy feature connected to the application, provide a way to analyze and figure out the most likely composition. It is in this context that I have been using the borrowed one, as a researcher. If Radiacode wants to step in and support my field studies, I will be happy to have my own unit, not a borrowed one.

I was looking at the Radiacore on and off for a week or two and finally just jumped on it. I don't have any experience with dosimeters/spectrometers, and was expecting the Radiacore to be a bit confusing to use initially but it was the opposite. The device is small, super simple to use and even without reading their website/manual only takes a minute to learn. The iOS app, while new and in development, also works flawlessly for current features and looks good. I love it when companies take the time to work on phone apps and theirs already looks great. Also super simple to pair, works instantly and you can edit the device settings from the phone app. Overall, this device clearly had a lot of effort put into it to make it work well for life and be sleek and small so it's not a hassle to carry around. Like double the size of a stick of gum. The price is absolutely worth it if you have a use case for it or are just an enthusiast that wants a better (and cooler) device to use.

This is a sweet piece of kit! If you're interested in identifying isotopes and mapping out your area for radiatioactive contamination you won't be dissatisfied with the 102. This is my first scintillation device so it's a super sensitive detector in my opinion. It makes for a great little device to have on while driving you never know what might be discovered. The phone app has tons of information more than I know what to do with as an amateur. I'm planning on taking it on flights to monitor excess solar and space radiation at altitude. With earth's magnetism decreasing the radiacode 102 is a great addition for those who like to know what's going on in our enviroment and what may be in our food.

As this is now my second detector, I can say that this device has met all my expectations. This product's sensitivity is exceptional to most sources that emit gamma, and it does a wonderful job making heat maps. The graphical user interface on the mobile app leaves some things to be desired, but these are mainly cosmetic changes; otherwise, the layout is excellent. I have noticed over the past few days of use that Bluetooth dropout can occur and that the application has to be completely quit and re-entered to reconnect the device wirelessly. Minor quirk, but the device continues to operate normally. Battery life is as expected with this device. I see about 4 days of use from 100% to around 20% before I recharge it. Note to those looking to buy this device, I do recommend a means to protect it from drops & scratches. The few extra dollars on a case or sleeve could potentially save the device from an otherwise unfortunate end!

Amazing product

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.
