Measure Radiation With The Safecast BGeigie Nano Geiger Counter

Start Measuring Radiation Today

Do you want to accurately monitor radiation? Then don’t just settle for an entry-level Geiger counter kit. Invest in the Safecast bGeigie nano so you can reliably collect research-quality readings like a professional.

If you’re looking for a high-quality, versatile counter… you just cannot beat the bGeigie.

All your data is geotagged so it can be uploaded to the Safecast map- where you can see radiation levels from Chernobyl to the Antarctic. With over 60 million data points on the Safecast map, you can learn a few things about environmental radiation… Plus, it even comes with a crushproof Pelican case so you can attach it to the outside of your car window and not worry about it.

That’s what we call RUGGED.

And no. You don’t need to be an engineer to put this kit together. In fact, you’ll be surprised at how easy it is to use and set up even if you’ve never done any soldering before: I was able to put the kit together in under four hours. We provide plenty of online instructions so you can seamlessly build the beige Nano kit (with some help from YouTube, of course).

Whether you’re interested in detecting radiation as a hobby or for a science project the bGeigie is “a FANTASTIC little counter”. So, if you truly want to know what things are radioactive near you then order this device today.




Safecast's Workhorse Radiation Device

The Safecast bGeigie Nano is part of a global environmental sensor network enabling University Researchers to personally collect radiation readings and freely use and share the data collected.

The Safecast bGeigie Nano is the only portable radiation detector with GPS and bluetooth.

You can take individual spot readings, or attach it to your car and drive around collecting geotagged radiation data that can be uploaded to the Safecast map.

Measures Alpha, Beta and Gamma radiation allowing spot contamination.

Upload readings easily using a smartphone and bluetooth, or later with logged data.

Access to the world's largest independent,  open and trustworthy radiation data set.


About Safecast

Safecast is an international volunteer driven non-profit organization whose goal is to create useful, accessible, and granular environmental data for public information and research.

Safecast maintains the largest open dataset of background radiation measurements ever collected - over 50 million readings to date and growing daily.

All of the data collected is available through an open, free and public map of all submitted radiation data readings that can be accessed via browser or smartphone.

We strongly feel that environmental data should be open, easy to access, and easy to understand for everyone. Independent opinions about environmental data have to be available. In the age of the Internet of Things, that voice can directly come from citizens.
