DescriçãoThe 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.
We hope you enjoy using GammaPix!
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 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. (This is particularly a problem with Motorola devices. We recommend against using GammaPix on any of their devices at this time.)
Not all phone models have been calibrated. The reported range will be large for devices without calibrations. Try out the app anyway. We'll rush calibrations for the most popular phones running the GammaPix Lite App.
This free Lite version requires a network connection to run and expires no sooner than Nov 15, 2012. To encourage you to use the latest version, upgrades will expire later. A full version with more features is planned before then, but we wanted to share what we've already built!
