Geiger Counter Nuclear Radiation Detector, High Accuracy Beta Gamma X-Ray Radiation Monitor, Professional Radioactive Dosimeter Digital Radioactive Tester with Sound Light Alarm

Decent housing. Buttons and controls are about what I expect on a non-professional detector.Easy to carry.Checked measurements/readings against locally published radiation range of 0.06 to 0.3 Micro Sievert per hour.The detector reads real-time 0.11/h to 0.4/h with an average of 0.13/h, and after 100 hours 13.6 mSGood enough for me

I bought it to test out a few things around the house and it did the job just right. Is nice and very portable. You set alarms on it for when it hits certain readings.

The media could not be loaded.  I do not know if this works? We put it under a CBP Backscatter machine which does emit X-Rays and did not measure any variance.

The Geiger Counter Nuclear Radiation Detector is an impressive piece of equipment, especially when you consider its price point. Here's a breakdown of its strengths and the reasons why I docked a star:Strengths:High Sensitivity: With its advanced GM tube and professional geiger counter core, this device's sensitivity is notable. It picks up beta, gamma, and x-rays efficiently and updates every second, a feature essential in a professional setting.Sound and Light Alarm: This is an excellent safety feature. Even if you aren't actively watching the screen, the sound and flashing screen alerts you when radiation levels are too high. This is particularly useful for those who might use this in a multitasking environment.Battery Life: The OLED display coupled with a rechargeable lithium battery is an excellent combination. A 2-3 hour charge offers an impressive 50-hour measurement capability, which is more than adequate for most needs.Compactness and Pen Clip Design: The size and design make it incredibly convenient. You can clip it on a pocket, bag, or any other location, making it readily accessible whenever needed.Versatility: Whether you're in a hospital, a geological exploration, or just checking the safety of your home after a renovation, this detector covers a wide range of applications.Areas for Improvement:User Interface: While it covers the basics well, the user interface could be a bit more intuitive. A more straightforward menu system or even a companion app might make the experience smoother for users who aren't familiar with Geiger counters.Detailed Documentation: For a device that serves such critical functions, the accompanying documentation could be more thorough in explaining the various readings and potential implications.In conclusion, for those on a budget seeking a reliable Geiger counter, this is a good pick. It does the job efficiently, and while there is some room for improvement, the strengths significantly outweigh the limitations. If you're in the market for a radiation detector that won't break the bank, this is a worthy contender.

Small and very transportable, with an audible tone that is acceptably loud enough.

Nuclear radiation. Uncontrolled high intensity exposure and cumulative moderate-intensity exposure can cause acute injuries and/or long-term stochastic injuries. Some low-level exposure from natural background radiation is unavoidable. Excessive or unwarranted exposure is best avoided. An acute radiation injury may eventually be observed. But the radiation that causes the injury isn't directly perceptible. If we can't perceive the presence of a hazard, we can't mitigate it nor manage our risk of injury. We need instruments that extend our perception so that we can recognize the presence and intensity of radiation before injury attains. Historically, such instruments have been: bulky, fragile, difficult to use, and/or didn't yield timely, actionable information. Times have changed.The size of a small MP3 player, this radiation detector is a very welcome addition to my 'hazard detection' kit. Charging the unit's internal battery is accomplished using a USB-C port, making it compatible with my USB-charging infrastructure. (A USB-A to USB-C cable is also included.) The user interface is reasonably intuitive. Being astonishingly small, the detector is easy to store, easy to transport, easy to use.Use may be discrete: turn down the volume, slip the detector into one's pocket, and no one around need be the wiser — unless, of course, one's radiation dose exceeds the set threshold, triggering an alarm. Use may be obvious: turn up the volume, turn on the particle detection sound, and wave the thing in the direction of potential radiation sources. All good.I've used the detector to do a baseline assessment of my home. Of particular concern was my rock collection. It includes some specimens of unknown provenance and some specimens that I picked up in the NV desert [think early atomic bomb testing]).Now part of my hazard detection kit, I'll deploy this radiation detector with additional instruments in my tactical vest during "urban exploration" of nearby historic sites and facilities. I live in an area where WWII was a growth industry. The war effort left many sites contaminated with radioactive material. Some sites have been mitigated. Many former military and civilian support sites have been repurposed, erasing features that could otherwise hint of latent hazard. Basic safety protocols entail instruments to detect and alert to such hazards.I also foresee some "stealth" use of this radiation detector. I'm of an age and temperament that, with some regularity, I'm accompanying friends to medical appointments. Some appointments are in hospitals. Some involve radiation or nuclear medicine. During some of these appointments, I've found myself anxious and distracted, unconvincingly repeating: "The Therac-25 incidents and the others were rare anomalies. The probability of something similar happening right here, right now is very, very low". My mantra is accurate: the probably of something similar attaining is very low. But this understanding is little comfort because the personal consequences of attainment are very, very high. Formal risk assessment of low-probability, high-consequence events has proven both vexingly complex and a site of ongoing contention. Informal risk assessment is subject to a wide array of cognitive biases. Rather than sit in the anxiety of an informal assessment or the frustration of an insufficiently powered formal assessment, I've decided to reassure myself by having an active radiation detector (this device!) in my pocket during future appointments — poised to alert if some untoward exposure threatens to attain. Peace of mind is priceless.

We haven’t had a need to test for nuclear radiation (thank goodness) but it gives us peace of mind having this in the house. We unboxed it and got it set up. It’s easy to use. We’re going to keep it in our box of energy supplies along with our battery radio and flashlights. Good product to have on hand!

Works great but battery life is less than 48 hours and when it goes dead it doesn't save a accumulative exposure data. Nothing more than a toy for a few days. Plastic pin broke after a few days.
