Technical Specifications

We’re exposed to background radiation every day of our lives. While some exposure to radiation is natural, higher concentrations can be the result of poorly shielded electronic equipment, X-rays, CT scans, or even air travel.

Beyond the substantial threat of nuclear meltdowns, disasters, and fallout, this excess background radiation can add up over the years and contribute to serious health issues. 

Fortunately, there’s now a practical solution you can take everywhere to monitor and measure your exposure—the MIRA Safety Geiger-2 Portable Dosimeter/ Geiger Counter.

Only slightly larger than a ballpoint pen, the Geiger-2 is a full-featured handheld dosimeter that offers the same reliability as a professional-grade Geiger counter at a fraction of the price and without the bulk. It’s built from impact-resistant polymer and has an easy-to-read LCD screen with two buttons, making it one of the simplest and most user-friendly dosimeters on the market today. 

Unlike traditional analog Geiger counters, the Geiger-2 is fully digital with various extremely useful features and modes. Customizable settings for exposure tolerances and long-term tracking of readings provide unrivaled clarity and customizability for various situations. Power management features can be used to optimize battery life and manage the included solar panel.

Best of all, the Geiger-2 tucks easily into a pocket, purse, or backpack, so it’s always ready when you need it—providing a potentially life-saving tool that makes you more aware of your environment and ready to face a range of twenty-first century threats. The first step toward protecting yourself from background radiation is identifying it with a reliable radiation meter.

The Geiger-2 is powered by an internal rechargeable LiPo battery with a 30-day extended battery life. Recharging takes just two hours.

NOTE: The integrated solar panel provides a supplemental trickle charge. It will extend the battery's 30-day charge when exposed to direct sunlight, but the Geiger-2 will still require regular recharging via the included charging cable.

It’s a perfect addition for bug-out bags and disaster prep, as it’s compact, reliable, and durable.

So, grab a Geiger-2 Portable Dosimeter / Geiger Counter and learn more about your environment today!


Ask a Question
  • Will this be able to detect radiation levels in water? I believe the previous one was able to so am hoping this one will be at least as good as the old one was.

    Yes, so long as the radiation is within the measurable quantity, it should be detectable by the Geiger-2.

So far so good.

Charged it and got familiar with the menu system. Hope I don't ever need to use it. So far so good.

So far so good

It takes some time getting used to how to operate it, but once you get it, it's a breeze. I love it so far. There is a flash light, mine works well. You have to hold the left button down on the first display screen. You just need to play with it and see how it's programmed. The manual isn't worth a thing. I wouldn't base anything off the manual. You might as well not even receive it. I honestly don't care about the manual because I prefer to learn about things interactively. When you first get it, plug it in, and let it charge to 100%. And then play with it. Try different button combinations. See all the features it has to offer. I love that you can see the tube through the window. It seems pretty durable. There's only a five year life expectancy on the device so know that in five years time you'll have to replace it, best case scenario. It looks very cool. It has a light indicator that flashes as a particle comes in contact with the tube. Also has an audible beeping indicator at a very low volume, which I understand for battery conservation and having a visual indicator makes it not an issue. It does have a solar panel on it, something you'd see on a calculator. I'm not sure how well that works yet. I'm happy with it. I have peace of mind for the next few years, assuming it holds up. And for that I'd say I paid a bargain. As far as the actual product, it's on the higher side. It's your basic tube you'd find in the most basic gieger counters, you're paying for the electrical components and overall design. I understand it costs money to develop your own product but a slightly lower price point would be justifiable. It arrived surprisingly quickly. Much better experience this time around versus past experiences. No regrets from me as of yet. Satisfied customer at this point in time.

Well put together

This is my second Geiger/ Dosimeter and I am very pleased with it. It took a little while as they were always sold out. I settled on a close competitor and while it was not bad ,I’m glad I decided to make a second purchase , a upgrade if you will. This meter is more consistent with its readings and I’m still learning the finer points of the meter, overall it’s easy to operate and understand what readings you are getting. Thank you.

Wow! Impressed and Big Tech upgrade

I've been in prepping mode for over a decade. Had considered Geiger counters, but wasn't sure. When Ukraine war came up, figured it would be a good idea to obtain one. Mira 1st gen went out of stock and so grabbed something off amazon. All other geigers out there are really inferior to what this offers. This is water resistant IP65, USB-C recharge, Solar Recharge! pleasing color display, lightweight, very compact, rugged, and MIRA reliability. Man its worth the price. Tested on some natural radioactive samples and works great! Good peace of mind with this vs Amazon products! Get yours now!
