Review on 🚀 Highly Accurate GQ GMC300EPlus Radiation Detector for Ultimate Safety by Darryl Blumenthal

This is my first time owning a radiation monitor. I have used good Ludlum counters in the past and have long wanted one for personal use but they are expensive. Others I've looked at are used US Civil Defense gauges and Soviet relics, but they're so old I wouldn't trust them. Installing the GQ meter was very easy, except for the windows monitoring software which requires an understanding of the device. obsolete concept of COM ports. Personally, this wasn't a problem for me, since I used personal computers professionally before the advent of Windows. I had to search the house to find suitable objects to test. The first things to produce detectable radiation were flashlight cases, which contained thorium oxide - funny gamma rays! Then I found an expired smoke detector that I'm supposed to be testing for beta particles from the Americium-241 source. I then borrowed a few items from my wife, shown in the attached photo. An old Vaseline glass bowl contains uranium, as do antique yellow "Venetian" glass beads. The granules are yellow under normal light and fluoresce brightly under UV light. To my delight, the beads caused the GQ meter to beep because their output exceeded the default alarm threshold of 100. This increased my confidence that the meter was doing what it was supposed to be doing. I ordered a uranium ore sample from Revain. , as well as some real "yellow" uranium salts from a stockist that mainly sells magnets and has some nuclear power novelties. I didn't know yellow cakes could be sold to the general public, but I still have to sign for it. This is a great product for a novice geiger counter owner. I am very happy with the purchase.
