Being able to detect radiation is a very useful thing in this day and age, especially after the 2011 Fukushima disaster (still ongoing), other US nuclear plant leaks and the Government's constant refusal to come clean on the real damage. The EPA won't help you either – they raised their "legally allowable" limits after Fukushima! The best thing to do is take matters into your own hand and find a way to measure the radiation yourself, for your own safety.
