Safecast's Workhorse Radiation Device

The Safecast bGeigie Nano is part of a global environmental sensor network enabling uranium miners and millers to 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.
