Developed initially for several federal agencies, turns your phone into a detector of ionizing radiation. The GammaPix technology has been successfully tested at independent labs with calibrated sources. It was developed with support from the U.S. Department of Defense, the Domestic Nuclear Detection Office (U.S. Department of Homeland Security), and the Transportation Research Board (U.S. National Academy of Sciences). We were encouraged by them to bring this technology to the public.Worried about accidental exposure to radioactive material or acts of terrorism? The GammaPix App can provide timely warning of the presence of radioactivity using nothing more than your phone's camera. While it is NOT meant to be a substitute for dedicated ionizing radiation detectors, it is a rapid and convenient way of making preliminary threat estimates.
We hope you enjoy using GammaPix!
Notes:
• Various circumstances may compromise the measurement or make the results inaccurate.
• Automatic monitoring will use ~1-5% of your battery, but could warn you of radiation even when not using the App.
• A 5 to 10-minute initialization is required before you use the application for the first time. We know this step slows you down, but it really is necessary to get the best results. Please perform this step in a place you know is likely to be free of excessive radioactivity, with your device cool and unplugged.
• For best results make sure no light is getting into the camera when you run the GammaPix App. Putting the phone in your pocket or covering it with a book works well.
• A reading takes about 3 to 5 minutes if there's no danger. Dangerous levels will be reported sooner.
• Try out Settings > Use long third stage for a more sensitive reading!
• The GammaPix App will not work on some phone models because the camera optimization at low light levels gives "bright" pictures.
• Not all phone models have been calibrated. We'll use your readings to provide a calibration for your model. The more you take, the sooner we'll have a calibration.

On my Google Pixel 8 Pro, it said the lens was uncovered and didn't work, even if I fully covered it. However, I tried it on a Google Pixel 4a, and it worked. It seems this app doesn't work on some phones, as they have an imbedded LED which bleeds infrared light into the camera. The light is invisible to the eye, but the camera's sensor can see it. If your camera sees a purplish light in its own reflection, it's incompatible. Even when working, it takes several minutes to complete a scan.

I have used your app successfully on cheap phones. I have a nice phone now and it just will not initialize the camera. It started off not allowing you to pic what camera to initialize. So I suspect the same is happening, trying to initialize both front and rear cameras and the screen noise, which the screen side camera is embedded in, is causing the whole things to fail. I did get through stage three and it said some phones won't work due to image noise. Why not allow the rear camera only.

This app does its job properly. For anyone not knowing, this app needs access to the camera because gamma rays can interact with the camera's sensor, showing a sort of "line". It needs completely dark environment (use black tape to cover lens) because to detect radiation, it measures the amount of light flashes in a determined amount of time. So, yes this app does indeed access the camera, for anyone concerned about that, but only if it is pitch black.

When I first opened the app and was at the stage before measuring, it told me to give permission to send me notifications, use approximate location then to switch it to presise. It also said that it would "measure on the background" and blah blah while it would be watching my presise location and collect data without me even knowing. I just agreed then I tried, and accidentally uncovered my lens. I tried again, and the app immediately crashed. Would not recommend at all. It's very bad quality.

This app is FAR too invasive for what it does. Requiring precise location permission even when the app is not running is absolutely not required as the app claims, this is a bold-faced lie. If the app is not running, it's because the user does not want to collect data. Do not presume to make decisions for your user base. We can decide on our own whether or not we want the app running and collecting data. Instant deal-breaker, and I have already uninstalled this snoopy app.

I am absolutely amazed at the concept that the developer employs here. I would really appreciate some explanation on the calibration aspects, as it always comes up with "all clear ". Is the actual background radiation used as the zero point? It would be a great feature to know background radiation levels in mSievert. Thnx

Seems to operate, but won't tell me enough. I want each camera's counts/minute, not just "All Clear" 😑. Even if your calibration for my model does not yet exist. (Does it? Tell me that, yes or no, in the app.) Let me text-label the location. And tell me the location it has received with my permission.

Refuses to work unless you give it full-time precise location access. Very suspicious. Should have the option to disable location, and definitely shouldn't need full-time access; while using the app should be sufficient, even if you want it to log locations.
