    works well
    I have some radioactive minerals in my area of the mountains so I got this so I know where they are.Picture is of a reading on an outcrop (thorite?). I rock-hound but don't want to be breathing this stuff! I can carry it when hiking and it will start the audio beeping when I hike over the hot spots.The mR/hr and micro Sv are accurate as measured against the calibrated instruments at work.The counter is high as measured against the alpha counter at work, possibly because it is counting more than just the alpha.Works great, good battery life.

    Reviewed in the United States on October 29, 2021
    I use This and other GQ electronics Geiger Counters two hunt for uranium glass in antique stores. I like the way it fluoresces under uv light. It is very easy to use and set up. The 600+ with its pancake tube can pick up zoomies from a fue feet away And it is very sensitive. A simple plastic bag or piece of paper will stop alpha detection. The battery life is outstanding You won’t be disappointed
