Geiger Counters / Radiation Detectors

This site was created to rate, review, and compare various Geiger counters and radiation detectors being sold on the Internet. While most Geiger counters appear similar, the fact is there are important differences in features, performance, and functionality! The focus is on devices falling within the consumer/commercial mid-range, from $100-$600. We present here a range of six devices to illustrate the breadth of product offering at this price range and to show which ones we believe are best.

At one time I was also looking for a Geiger counter to warn about potential radiation hazards, whether from radon laced granite countertops, contaminated scrap metal, nuclear plant discharge, depleted uranium waste, or even something as simple as in-flight atmospheric background radiation. I was shocked to learn how much low-level radiation we're exposed to every day. Even at home there are unexpected sources I hadn't ever considered. So while the possibility of a dirty bomb exploding nearby seems remote, I can easily see the benefits of owning a personal detector to tell me if I'm being exposed to harmful levels, even if relatively low.
