I can't vouch for accuracy as I don't have anything to compare it to, but I put it close to my smoke detector (they all contain Americium) and it did pick up the radiation.Very easy to use, highly recommended! ### ⭐⭐⭐⭐⭐ Excelente equipo de medición! *by on Reviewed in Mexico 9 November 2024* Es un excelente equipo de medición de radiación ionizante, lo verificamos con la radiación de fondo del lugar en donde nos encontramos y es muy preciso!Obviamente al igual que cualquier otro instrumento de medición si se requiere conocer su porcentaje de error o fluctuación para mediciones mas certeras se debe hacer la calibración correspondiente con un laboratorio acreditado!Sin embargo, los datos que ofrece son muy cercanos a los reales!No le pide nada a marcas más avanzadas en este tipo de equipos de medición!Y la realidad de las cosas es que este tipo de equipos ya se han vuelto una necesida, debido a que la radiación ionizante se encuentra en muchos lados, no sólo por la presencia de plantas nucleares, existen sitios en diferentes partes del mundo que tienen radiación ionizante ambiental muy elevada o equipos que la generan, y es importante conocer los valores de referencia para no exponerse innecesariamente a la radiación ionizante debido a los efectos biológicos que pueden producir, ya sean deterministicos o estocásticos (ICRP, 2007).Lo recomendamos ampliamente!Saludos cordiales! ### ⭐⭐⭐⭐⭐ Fascinating as a toy besides its more practical uses *by on Reviewed in the United States 26 October 2025* A very affordable and well made item with a large, colorful display that is easy to read and with pages and pages of different displays allowing you to customize what you want to see and how you want to see it. This is a "smart" device that can link to your PC and through the cable, the battery is kept charged for two or three days of field surveys. More if you turn it off between uses.I bought this just for the fun of detecting uranium in the Chinle and Morrison geologic formations of the Colorado Plateau and seeing for myself that genuine dinosaur bones and petrified wood from those formations can be quite radioactive. As mentioned, I bought this just for fun and not for any practical, safety or economic reasons. Unfortunately I have not had an opportunity to use the device for its intended purpose, but I have confirmed that the unit is functioning well.It sure would be nice to have a counter that displayed actual EVs of the radiation so that I could tell just what radioactive elements are present, but they cost more and for me, it just for a whim more than anything else.When visiting dinosaur museums, I'll turn off all alarms and sounds so as not to panic the public if a bone proves to be a bit "spicy" and I recommend others do so too. ## Frequently Bought Together - Nuclear Radiation Detector GQ GMC-800 Geiger Counter USA Design Product US National Standard Large Color LCD Display 5 Alarm Types Dosimeter Data Save & Global Share Beta Gamma X-ray Portable Device - FBLFOBELI Hard Case for GQ GMC-800/GMC-320S/GMC-300S/GMC-300E/FNIRSI GC-01 Geiger Counter Nuclear Radiation Detector Monitor Meter - Potassium Iodide Tablets 130 mg | 120ct Iodine Tablets for Radiation Exposure - Potassium Iodine Pills - YODO Naciente - KI Pills - Made in USA - ThyroShield --- ## 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.us/products/680265516-gq-nuclear-radiation-detector-gmc-800-geiger-counter-usa-design](https://www.desertcart.us/products/680265516-gq-nuclear-radiation-detector-gmc-800-geiger-counter-usa-design) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-24*
