GammaPix
Unlike the Lite version, this App only require a network connection to operate after several days. We recommend you update GammaPix from time to time to check for new calibrations.
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 10 to 20-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.

Once again this latest 'update' has rendered your previously working app non-functional on my device. Once you have it working, LEAVE IT ALONE!
GammaPix doesn't work at all and says light is getting to the camera when the camera is completely covered.
Also when will the calibrations for Samsung Galaxy S6 be out?
Does not exist at this time. Cannot use App properly as the measurements may be skewed.
No calibration for samsung galaxy note 3, please add calibration then 5 stars.
Five stars when it gets calibration for galaxy s5
This app used to work, giving me a specific level regardless of "safety" Now it just says "safe" for low levels, making it useless. Even if low levels are in accurate, comparing them to a background level were useful for comparison. I used to be able to detect monazite vs background, or potassium chloride, or 10%thorium welding wire. Now I get nothing. I want to test for radiation existence, not safety, so this device is useless. It can't even detect being in an airplane, which is 3x background during the day, and 2x night time background at night. It made a useful tool useless.
App failed to identify presence of Co-60, Sr-90, Cs-137 sources in nuclear engineering laboratory using Samsung Galaxy S3. Zero microsieverts were registered both away from sources and in close proximity, and at all distances in between. Test conducted twice, with identical results. Installation and setup of app was easy, though I am not confident in the results, at least on the phone used to test.
Ignorance isn't always bliss. A fine app giving useful results. I recommend it highly :-)
No calibration for the galaxy s3, which is a pretty popular phone. It still initialized successfully, however my phone picks up radiation in my night stand where I initialized it and not my decade old microwave. I plan to keep the app for when my phones fully supported though, it deffinitly works.
Does what it says on the tin. Installed fine but tells me no specification for Galaxy S4 so only an approximate calibration was carried out? As above .
No mater how much I cover the camera it keeps telling me the initiation failed. Nexus 10
The app repeatedly locked up, as well as prevented me from using the camera even when the app wasn't running. I received one response from support suggesting I reboot my phone. What good is an app if I have to reboot my phone everything I want to run it? Still no response from tech support to my earlier query. Avoid this app.
(((For Latest Version))) Doesn't work well with a Samsung Galaxy Tab S2. I collect Uranium Ores all of my samples put out at least 30,000 CPM of gamma and beta, not counting alpha. The app only reads 13.5 mSv per hour on my most radioactive thing I have which is a source disc of 10 uCi of Cesium 137.
