There are apps that are trivial and ones that are not. An app that can detect radiation and can be used to discover potentially deadly threats, measure the radiation dose received while in flight, or search for orphaned radiological sources is far from frivolous.
The GammaPix technology is based on analysis software that operates on the images produced by a surveillance camera, webcam or smartphone to measure the local gamma radiation exposure at the device. Within seconds, this software displays the level of gamma radiation in the immediate area.
While radiation is ubiquitous, GammaPix can provide early warning of unusually high levels of radiation from rare events such as the nuclear accident in Fukushima, Japan or lost radioactive sources.
The GammaPix technology has been successfully tested at national labs. 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).
This app is of particular interest to first responders. Also, the military is evaluating beta versions of GammaPix. The app is currently free and is compatible with Android (and is expected to be made compatible with iPhones soon).
Image Insight plans to implement a crowd-sourced capability to enable users of GammaPix to upload their readings of radiation so that fellow app users will know where radiation risks are located.The Radiation Detection App ,
