Or radiation from dirty bombs?** A: The GMC 320 Plus's upper range limit is 32 millirem per hour. (A millirem is 1/1000th of a rem). According to the scientists at the Oak Ridge National Laboratory, a Facility of the U.S. Department of Energy, in their 1987 "Nuclear War Survival Skills", small doses of around 6 rem per day should "produce no incapacitating symptoms. The human body usually can repair almost all radiation damage if the daily doses are not too large." They go on to say, "Instruments that measure only milliroentgen-range dose rates are sold for war use by some companies. Since most Americans have no idea what size of radiation doses would incapacitate or kill them, and do not even know that a milliroentgen is 1/1000 of a roentgen, some people buy instruments that are capable of measuring maximum dose rates of only one roentgen or less per hour." (One roentgen is equivalent to one rem.) The book further says that a meter that "can measure one roentgen (rem) per hour is far too low to be of much use in a nuclear war." **Q: I'm a novice wanting to check for radiation levels. Is this device easy to understand? What can I use this for to measure for radiation?** A: The GMC-300 is easy to use and low priced as an entry level radiation detector. I use mine to monitor background levels of radiation as I have yet to find an highly active source. Here in central BC, Canada I get 14 to 22 cpm, with a high of 30 cpm. It appears to decrease after a rain fall. The only thing missing with the GMC-300 is a radiation standard but I can understand why. **Q: Will this measure the radiation level present in gemstones?** A: Not all gemstones emit high enough levels of radiation that can be discerned above ambient levels of radiation and it depends on the actual level of radiation the stone emits. Stones that have been exposed to radiation to change their color will probably not register. I have some uranium marbles that are not detected by this counter. My wife was subjected to a PET scan, last year and read 790 CPM from a distance of 6 feet. **Q: can I use this to measure Fukushima radiation in seafood?** A: I've read articles regarding radiation in seafood indicating the levels you read may be may be misleading. The GMC-300 will measure this radiation. Here in Northern Indiana the ambient level is normally 30 - 40 CPM. As shown in the video, levels in sea life can be higher. http://www.opb.org/news/article/scientists-say-stop-worrying-about-fukushima-radio/ Rick ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best quality *by A***R on 25 October 2025* Super Duper quality, go for it ### ⭐⭐⭐⭐⭐ GMC machine *by M***R on 19 March 2025* Great Machine it works acurate ### ⭐⭐⭐ Performance *by R***N on 5 December 2025* Ok ## Frequently Bought Together - GQ GMC-300E Geiger Counter Nuclear Radiation Detector Data Recorder Beta Gamma X-ray - WERJIA Hard Carrying Case for GQ GMC300 Plus/GMC-320 Plus Radiation Detector - Potassium Iodide Radiation Tablets 130 mg (2 Pack) - (280 Tablets) EXP 10/2032 - Potassium Iodine Pills YODO Naciente, Anti Nuclear Fallout Pills --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/82334037-gq-gmc-300e-plus-digital-geiger-counter-nuclear-radiation-detector](https://www.desertcart.vn/products/82334037-gq-gmc-300e-plus-digital-geiger-counter-nuclear-radiation-detector) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-04-26*
