MIRA Safety Geiger-2 Portable Dosimeter Radiation Detector

***Estimated Delivery: 3-4 weeks

*Due to the nature of this product, returns/exchanges cannot be accepted”

The MIRA Safety Geiger-2 is a pocket-sized digital dosimeter and Geiger counter built around the same SBM20-01 Geiger-Mueller tube found in professional-grade radiation detection equipment. Powered by a 400 mAh rechargeable LiPo battery with a 30-day charge life and supplemented by an integrated solar panel, it detects radiation levels from as low as 0.999 μSv/h up to 999 μSv/h. A full-color 1.1-inch LCD, two-button operation, and USB-C charging make it practical for daily carry, emergency preparedness kits, and disaster response scenarios alike.

Who this is for

  • Emergency preparedness planners: anyone building a bug-out bag or household disaster kit who needs continuous, real-time radiation awareness after a nuclear incident or industrial accident.
  • Everyday carry users: individuals in urban environments who want ongoing background-radiation monitoring during air travel, near medical imaging equipment, or around poorly shielded electronics.
  • First responders and professionals: personnel who require a compact, rechargeable dosimeter that tracks long-term cumulative exposure and triggers audible alarms at customizable thresholds.

Detection range and performance

The Geiger-2 uses the SBM20-01 Geiger-Mueller tube — the same tube used in professional-grade counters — to detect alpha particles, beta particles, gamma radiation, and X-rays. It reads radiation levels from 0.999 μSv/h at the low end up to 999 μSv/h at the high end, updating output every 20 seconds as a count rate in counts per second (CPS). That 20-second refresh cycle gives a responsive, real-time picture of ambient conditions without burning through battery capacity.

For long-term tracking, the device stores historical exposure data and lets you set customizable daily exposure limits. When those limits are reached, an audible alarm fires. This combination of real-time monitoring and cumulative dose logging makes the Geiger-2 functional both as an instant-read radiation meter and as a true dosimeter for multi-day field use.

Power system

The internal 400 mAh, 3.7 V LiPo battery delivers a 30-day operational charge under normal use. A full recharge via the included USB-C cable takes approximately two hours. The integrated solar panel provides a supplemental trickle charge that extends battery life during daylight hours — it does not replace USB-C charging, and only indirect sunlight should be used to charge the device through the panel.

Construction and portability

The Geiger-2 is built from impact-resistant polymer and measures only slightly larger than a ballpoint pen. At that size, it fits in a shirt pocket, jacket pocket, purse, or backpack side pouch. The full-color 1.1-inch LCD displays key readings at a glance, and the two-button interface keeps operation straightforward regardless of experience level. In the box: the Geiger-2 unit, a keychain, a carabiner, and a USB-C charging cable. The device operates in temperatures as low as 51°F (10.5°C).

Frequently asked questions

What types of radiation does the Geiger-2 detect?

It detects alpha particles, beta particles, gamma radiation, and X-rays using its SBM20-01 Geiger-Mueller tube. The tube ionizes when exposed to radiation and generates an electrical pulse the device counts and displays in real time.

What is the difference between a Geiger counter and a dosimeter?

A Geiger counter measures current radiation levels in real time, while a dosimeter tracks the accumulated dose over a period of time. The Geiger-2 functions as both: it displays live CPS readings and also logs cumulative exposure so you can monitor your total dose across days or weeks.

Can the Geiger-2 detect radiation in water?

Yes. As long as the radiation level falls within the device's 0.999–999 μSv/h measurable range, the Geiger-2 can detect it regardless of the medium.

How long does the battery last and how do I charge it?

The internal LiPo battery lasts 30 days per charge under normal use. Recharging via the included USB-C cable takes approximately two hours. The integrated solar panel extends that 30-day charge in direct sunlight but does not eliminate the need for regular USB-C recharging. Use only indirect sunlight when relying on the solar panel.

Can I set custom radiation alarms?

Yes. The Geiger-2 lets you set customizable daily exposure limits. When the accumulated dose hits that threshold, an audible alarm activates. This feature is particularly useful for users who want a safety ceiling during extended exposure scenarios such as nuclear disaster response or repeated medical imaging.

Is the Geiger-2 reusable long-term?

Yes. It is a fully digital, rechargeable device with no consumable components. The LiPo battery recharges via USB-C, long-term exposure statistics are stored onboard, and power management settings let you optimize battery performance over months and years of continuous use.

The Bulletproof Zone Promise

When you buy body armor, you're buying your safety. We don't take that lightly. Here's what every order from Bulletproof Zone includes.

1. Authorized dealer of every brand we carry

Every plate, vest, and carrier we ship comes from the manufacturer directly to our warehouse. We don't sell gray-market product, surplus, or returns. That means factory-fresh stock, the full manufacturer warranty, and real after-sale support — the kind only an authorized dealer can offer.

We maintain authorized-dealer relationships with America's leading body armor brands, including Spartan Armor Systems, AR500 Armor, RMA Defense, Shellback Tactical, Caliber Armor, DFNDR Armor, Protection Group Denmark, BulletSafe, BulletBlocker, and over 40 more.

2. Best price, guaranteed

If you find a lower price at another authorized dealer of the same product within six months of your purchase, we'll refund the difference.

Why the "authorized dealer" requirement? Because gray-market and surplus armor may not be genuine, may have a compromised supply chain, and almost never comes with a manufacturer warranty. We won't price-match against products that may not actually protect you.

3. Free fitment consultation

Body armor only protects you if it fits. Email us a photo and your measurements before you order, and one of our specialists will help you size your carrier and plates correctly — at no charge, no obligation.

4. Trusted by thousands of customers

Bulletproof Zone has been a trusted authorized dealer of America's leading body armor manufacturers for over five years. We have over 4,000 verified Trustpilot reviews from real customers across all 50 states.

  • You must have purchased the item from our website before requesting the price match.
  • Discounted items and "free with purchase" items are not eligible.
  • The item must be in stock on the competitor's website at the time of your request.
  • The price match is valid for six months from the date of your purchase.
  • The competitor must be an authorized dealer of the product. Auction sites (eBay, Overstock), discounters, and gray-market resellers do not qualify.
  • The competitor must operate an online store. Brick-and-mortar-only retailers do not qualify.
