Geiger Counter, Radiation Detector, and Dosimeter Reviews and Ranking

For more than 6 years we’ve compared, reviewed, and rated the world’s most popular handheld Geiger counter. While most portable Geiger counters appear similar, the fact is there are important differences in features, performance, and functionality. Our focus is on personal geiger counters within the consumer/commercial mid-range, from $100-$600. We looked at functionality, construction, ease of use and of course, price – 6 dosimeters that illustrate the breadth of product offering now available.


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. Now with the possibility of a dirty bomb attack even more apparent, it’s easy to see the benefits of owning a personal dosimeter to tell me if I’m being exposed to harmful levels of radioactivity, and to protect me in case the unthinkable becomes a reality.
