## Description

Product Description Nuclear Radiation Detector Geiger Counter GQ GMC-800 (Patent Pending) . About GQ Nuclear Radiation Detector Geiger Counter Radiation Detector Geiger Muller Counter The GQ GMC-800 Nuclear Radiation Detector Geiger Counter is the newest enhanced member of the GQ GMC family, developed, final assembled, and quality tested at GQ Electronics, Seattle, USA. This radiation meter detects Beta, Gamma, X-ray nuclear radiation quickly and precisely, detecting changes at fast speed. The GMC-800 is the most cost-effective multi-functional nuclear radiation detector, loaded with features. Accurate, Trust-able, Reliable The GMC-800 radiation detector device passed the USA NIST ( National Institute of Standards and Technology ) and NRC ( Nuclear Regulatory Commission ) standards. Each device is calibrated before shipment, and users can also self-calibrate down the road to maintain longevity. About GQ detector serial products As consistent with GQ's Geiger Counter product line, many unique & advanced features have been integrated into the meter while maintaining affordability. GQ models have more features than any other brand products in the marketplace, all at a similar price and even cheaper than a lot of the more expensive models. 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: ..........................................................

Do not use adapters with a voltage above 5V, including 12V or higher. 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. User Friendly Interface UI The user interface (UI) is carefully designed to delight users Simple to use: Simply power on and instant reading; One key press switch the function screen. Easy to access and change the battery Easy to navigate across the menu Intuitive & information well organized. Large color bright clear TFT LCD display. Display contrast and the backlit brightness are adjustable accordingly.

Review: Accurate and pocket friendly - Perfect for my needs. I wanted a good balance between price, accuracy and quality. After several days of reviewing many radiation detectors, this one kept coming up as a highly rated product for its price point. If like me you are mainly interested in having this as a preparedness tool and playing with from time to time, I would highly recommend this device.
Review: First reliable low cost high accuracy calibration pocket geiger counter on desertcart - For this review, I've uploaded my side-by-side background radiation comparison photos of this new American GQ GMC-800 Geiger Counter with the readings given by two far more expensive high-end, calibrated scintillation counters: a Thermo Radeye with external dual phosphor probe, and a Radiagem with a 2x2" NaI phosphor external gamma probe. The background readings are in a relatively high background region of Cornwall, not very far from the old South Terras Uranium Mine). Note that 300 nSv/hr = 0.3 uSv/hr, so that a GMC-800 reading of 0.3 uSv/hr is identical to the Radiagem's 300 nSv/hr. The American GMC-800 is accurate, lightweight, pocket sized and has just the features you need to rapidly check background gamma radiation. It will display counts/second, milli-Roentgens per hour (for the imperialists), uSv/hr, or counts/minute. The GMC-800's manufacturer's geiger tube gives 25 counts/second per mR/hr or per 2.5 uSv/hr (they use the RBE=1 conversion whereby 1 mR = 10 uSv). It also functions as a dosimeter, so you scroll through the options to display accumulated dose. You can also set the alarm threshold however high you like. Accuracy is within +/-20%. It comes with USB data and charge cord, a 3.7v lithium ion rechargable battery (AA sized) which is removable via a battery cover on the back, a soft dust proof case, and instructions plus radiation safety data "credit card" for a wallet, listing radiation levels and precautions needed. To turn it on, you need to hold the on/off button down for 4 seconds (probably to prevent it accidentally being turned on or off by keys or change in your pocket). The only disadvantage is that the AA sized 3.7v lithium ion battery cannot be substituted for a common AA 1.5 v battery in an emergency (it needs over 3v and won't work with a common 1.5v AA battery, I checked this). So you might want to buy a spare 3.7v lithium ion AA sized battery, or take a USB charge cable and portable phone charging power pack with you, if you want to ensure you don't run out of power. By default it makes a soft click every time a gamma ray is detected, the LED light above the display screen flashes with every "count". You can customise these settings. I have previously "tried" to buy two cheaper pocket geiger counters of other brands on desertcart, but both have been defective and been returned (I don't like reviewing totally defective products, as there's nothing to say and of course occasionally items are damaged in transit so you can't necessarily blame the product itself, which would create a misleading "review"). This American GMC-800 is brilliantly designed to do a straightforward job, does that job well, and I recommend it to anyone who needs to measure radiation.
