Your Android Phone Can Do Double Duty As a Geiger Counter

Android: While we’d hope you’d never need it, clever researchers have figured out how to turn the camera on your Android phone into a makeshift Geiger Counter with nothing more than an app and some black tape.

It’s not as versatile as a true Geiger Counter (it doesn’t measure as broad a spectrum) but for a free application that could be quickly deployed during an emergency to the hundreds of millions of smartphones floating around, it’s pretty awesome. From the app author’s web site:

This App is not one of those numerous “fun apps”, but a true, really working radiation detector. We already did measurements for certain devices using professional equipment at the Helmholtz Research Center Munich, the scale we used for testing starts at several 2-10 µGy/h up to 10 Gy/h (about 10Sv/h) with the latest measurements
