Nuclear Radiation Detection Ionizing Radiation Unlike EMF radiation, nuclear radiation is an ionizing type of radiation. The nuclear radiation sources include natural and man-made technology. Both impacts living creatures’ daily life and earth environment. Under circumstances, nuclear radiation can be life-threatening, with food, water, and even air can be contaminated with dangerous particles. Nuclear bombs being the great offender. Generating nuclear radiation from man-made technology is a serious problem worldwide. The meter can detect radiation from materials alike the following: Cosmic Rays, Radioactive Rock, Collectible Antiques, Plates, Watches, Nuclear Plant Leakage, Atomic Bomb, Nuclear Fallout, contaminated food etc. Specifications Range of dose rate indications, µSv/h: ......................... 0.00 to 2000 _________________ Detectable Radiation Range: ................... 0.1 ~ 3 MeV Range of exposure dose rate indications, mRem/h ..... 0.00 to 200 _________________ Working Voltage: ........................................ 3.6-3.7V Range of registered beta radiation energy MeV .......... 0.25 to 3.5 __________________ Display: ..........................................................

GQ GMC-800 Multifunctional & Usage Geiger Counter Dosimeter Radiation Monitoting Real Time Time-frame GQ GMC-800 is multi-functional, can be used as traditional Geiger Counter with clicks, real time & certain time frame measurement, dosimeter accumulation radiation on user body, continues radiation monitoring for certain location with certain time-frame. As a traditional Gieger Counter: find the instantaneous radiation flux on a location/spot. Traditional finding radiation source application As a dosimeter multiple dose units: detect the real-time & accumulated radiation on human. Reading in different units shows at the same screen As a Real-time & time-frame measure: display real-time radiation and time-frame radiation data and record and save data. As a Radiation monitor (Graphic): continuous monitoring a location radiation over time. The unit can be connected with computer to monitor. Ergonomic Design & Two Ways Power Supply Mechanical Design Light (~4 oz) Thin (~half in thickness) make it portable, easy to carry Premium material is used to realizes Anti-drop & robust Where to Put the Detector Handheld Put in the pocket Stand up on both edges (short & long edge) Lay on the surface Power supply Charge & Data trasmission There are two ways to supply power. In-unit battery or power via USB port The charging cable is Type C Type C USB cable also facilitate data transfer Battery Charge & Replaceble Lithium Ion rechargeable battery The battery can be take out any time for external charger. The battery is also replaceable when goes bad Battery can be charged in meter or take out charge via external charger The device detects battery orientation and halts charging if positioned incorrectly to protect itself. Five Ways to Alarm When the Radiation amount Exceeds the threshold Radiation Alarm Visual, Audio, Vibration, Color Bar, Voice Alarm threshold can be set by user. While the radiation exceeds the threshold, this device will alarm in 5 ways that will not omit anyone. Visual Top middle LED alarm: the LED blinks in red Screen visual color bar alarm: the indicator moves from green to Red Click sound audio alarm: unpleasant click sound & noise Vibration alarm: the meter vibrates for quiet environment, Voice talking alarm: people voice remind and alarm for vision impaired.

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! Review: Excelente equipo de medición! - 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! ## Features - 【Nuclear radiation detector】GQ GMC-800 is the latest upgraded model of USA GQ Electronics Geiger Counters.

Saludos cordiales! ### ⭐⭐⭐⭐⭐ Fascinating as a toy besides its more practical uses *by J***G on 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.hr/products/572111584-nuclear-radiation-detector-gq-gmc-800-geiger-counter-usa-design](https://www.desertcart.hr/products/572111584-nuclear-radiation-detector-gq-gmc-800-geiger-counter-usa-design) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-07*
