GQGMC-300S Digital Nuclear Radiation Detector Monitor Meter Geiger Counter Radiation Dosimeter

So far so good, you would be suprised how much radiaton is in the world.

Great basic Geiger counter. Only change I would make is for counting mode of come-up when external power is applied, not the charging progress. I like to have various meters in my car and don't like turning them on everytime. If you see one of the $10 cheap import meters, just bite the bullet and get this instead.

I got this because I always wanted a geiger counter, for no specific reason. It really works well it's rechargeable it's compact and you can read different settings from it. I took it to the dentist and it didn't really register any radiation. When the dental Tech pointed the little x-ray gun at it it went a little nuts.

4 stars because it takes a long time for the CPM to go up. Wish it was more instantaneous.

This is awesome product. Works exactly as it should. Precise and reliable. German products are still top notch. I would buy it again.

The media could not be loaded. It works pretty good! It does not detect alpha radiation as shown. On uranium glass it does take a while for the CPM to go up. On more radioactive stuff like old fiestaware it does it pretty quickly. If you take the back off it will show even more shown in the video. I don't recommend doing it though if you don't know what you are doing! The tube is fragile and so if you take the back cover off, you have to be super careful!

Works as advertised! Great tool to check for radiation on Big Ben wind up clocks with radium dials.

I got this to monitor the radiation during and after my RAI therapy. For the most part, it seems accurate. The first 24 hrs of my RAI, the radiation from my neck area was off the charts. It was interesting to see but also scary. I used it as a way to determine the distance to keep myself far enough during isolation. As the radiation decays, the distance you radiate becomes less too. I also used it to monitor the radiation from my pillow. I have a favorite pillow and the neck area was still high in radiation. It took about a month and a half for the radiation to come back down to normal levels. Even the pillow cover was still high in radiation too. Having this tool really helped ease my worries about radiation and affecting those around me. It was well worth it. Hopefully I don't have to go thru that again. For those that do go thru something like RAI, this tool is helpful and I wish you a speedy recovery.
