Safecast's Radiation Geiger Counter: bGeigie Nano. Portable radiation detector with GPS and bluetooth.
The Safecast bGeigie Nano is a mobile, GPS enabled, logging, radiation sensor used by anyone that wants reliable radiation readings including scientists, first responders and citizens. It is designed for mounting on the outside of a car window but can be used on bicycles, trains, planes, and other modes of transportation.
The bgeigie nano is weather resistant and rugged. It can also be used for taking static readings and contamination findings. In logging mode, the Nano takes a measurement every 5 seconds and logs the time and location coordinates.
With the bluetooth option, the bGeigie works with your smartphone. Install the Safecast:Drive app on your Apple | Google Play | Amazon Apps device and upload your data on the go!
Nano users submit their log files to the Safecast dataset and can view their readings on the open and free Safecast map.Joe in Fukushima preparing to fly a drone with a mounted bGeigie. Read more.

Example Test Before Shipping Fully Assembled bGeigie Nano
The bGeigie Nano is a solid-state, fully digital device. Because of its design, its performance is extremely consistent, and unlike devices with analog components which can be affected by temperature and other effects, further calibration is not expected to be necessary.
bGeigie Nano units have periodically been put through stringent calibration tests at QualTek in the US, at the Jülich Research Centre in Germany, and at the IAEA testing laboratory in Seibersdorf, Austria. In all cases the measured accuracy has been shown to be compatible with the SAFECAST specifications (Accuracy: +/- 10% typical, +/- 15% maximum ). Please note that +/- 10% is currently considered excellent performance for a Geiger counter.
This device is part of a global environmental sensor network enabling people to personally collect radiation and air quality readings, and freely use and share the data collected.
One of the things that differentiates the Safecast bGeigie nano from other geiger counters, is that it takes extremely fast alpha readings which allows you to perform spot decontamination.
Safecast is a global environmental sensor network enabling people to collect radiation and air quality readings and freely use and share the data collected.
Started after the Fukushima earthquake in 2011, Safecast has the largest collection of radiation data ever available spanning every continent on the globe. The project is driven by volunteers and citizen scientists everywhere, just like you.
Safecast believes that environmental data should be open, easy to access and easy to understand. They provide an open, free and public map of all submitted radiation data readings that can be access via browser or Safecast:drive apps.
Note: A portion of this sale is given back to Safecast for continued development and education of open source environmental monitoring and data accessibility.
