GammaPix Lite

GammaPix Lite


The GammaPix(TM) Lite App, developed initially for several federal agencies, turns your phone into a detector of ionizing radiation. This isn't one of those fake Geiger counters. 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.

Version 2.1.0 has all new functionality including:
o Automatic monitoring for radiation when you're not using the app.
o Use either camera.
o Choice of radiation dose units.
o Better handling of noisy cameras

A full version with even more features has been released. Check out GammaPix™ for real-time readouts of your results! The full version does not require a network connection to run.

We hope you enjoy using GammaPix!

Notes:
This is a tool. Various circumstances may compromise the measurement or make the results inaccurate. 


A 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.

For best results make sure no light is getting into the camera when you run the GammaPix Lite app. Putting the phone in your pocket or covering it with a book works well.

A reading takes about 3-5 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. Try out the app anyway.

This free Lite version requires a network connection to run and expires no sooner than December 23, 2014. To encourage you to use the latest version, upgrades will expire later.

This app will kill your batery After I installed this app, my battery started going down at the rate of 10%/hour. I had to uninstall it (which fixed the problem).

Nexus 5: best with front camera. Tested on top of a thorium-based gas mantle for which my Pocket Geiger probe (also semiconductor-based) registers 2 uSv/h (40 counts per minute). GammaPix registers 0.0 uSv/hr on the rear camera, and about 7 uSv/hr on the front camera. (Front cams are more sensitive, according to help) * * * Criticism: device initialization didn't work the first time; needed to clear and re-init (and reboot) to get it to work. App should really provide confidence intervals (does 0.0 uSv/hr really mean that, or "less than 1 uSv/hr")? App needs way to disable background measurements - I'm not comfortable with this app taking photos in the background.

Not sure Doesn't have calibrations for my LG G3, also when I try to use the rear camera it says "too low quality" but seems to work with my front camera. Of course it reads background at home. I'll try again once I have access to some calibrations sources. Hope my problems will be solved so I can give a full 5 star which I think it deserves.

Crash crash crash Crashed upon startup, during calibration and whenever it actually initialized... not worth the space. LG G3 as test platform.
