It might surprise you to learn that it is completely legal to listen to official police scanner radio transmissions in the United States.

Ambient radiation is naturally surrounding you at all times, but it’s almost never dangerous. The radiation levels are too low to be a problem. But there are areas where it is higher than normal and potentially-dangerous. Those areas are almost always clearly marked by the country’s government, but it can be fun to see if you can find “hot spots.” To do that, you’ll need a way to measure radiation. Instructables user prabhat_ has a tutorial explaining how to build one of the most feature-packed Geiger counters we’ve ever seen.
