The bGeigie Nano is our primary workhorse mapping device. This is a mobile, GPS enabled, logging, radiation sensor. Designed for mounting on the outside of a car window, it can also be used on bicycles, trains, planes, and other modes of transportation. In addition to mapping, it can be used for taking static readings and finding contamination. In logging mode, the Nano takes a measurement every 5 seconds and logs the time and location coordinates in a format designed to integrate perfectly with the Safecast Dataset.

The “Kids Geigie” is a simple breadboard based geiger counter kit that can be assembled and disassembled within 60 minutes and is capable of performing simple measurements when linked to the Safecast app on an iPad or iPhone. We use these kits as part of educational workshops in conjunction with videos and curriculum to help introduce younger students to environmental monitoring and DIY electronics.
Conceived and designed primarily by OG Safecaster Ray Ozzie, the Solarcast device combines everything we’d previously learned deploying our bGeigie mobile radiation sensors, Pointcast fixed radiation sensors, and the 2016 Safecast Air beta test. It is intended to provide convenient, hassle-free, independent operation. This device is solar powered, providing both radiation and air quality monitoring and cellular connectivity making it our first truly wireless, autonomous. Due to several deployment complications we’re not producing more of these devices, though the existing models continue to function well in the field. The Solarcast Nano and forthcoming Solarcast Nano Air replace this in our lineup. Read more about the Solarcast here.
A smaller & more convenient radiation only version of our larger and more cumbersome Solarcast, the Solarcast Nano is our ideal “drop and forget” realtime monitoring solution. Global 3G connectivity and solar power, combined with an almost pocketable size mean this can go anywhere, anytime, and keep working on it’s own indefinitely. We use this for our closest sensor deployment to Fukushima Daiichi and all foreseeable realtime radiation monitoring solutions will be based around this device.

Our initial fixed sensor network was deployed in the immediate aftermath of 3/11 with the intention of providing ongoing measurements from specific locations primarily in Fukushima. Each Pointcast device required existing infrastructure and a labor intensive custom installation. Ongoing maintenance, updates and trouble shooting had to be done in person, with only a few volunteers being able to fill that role. This resulted in poor functional reliability as devices would be offline for weeks or months at a time awaiting service or relocation. These devices are now depreciated and being replaced by our newer solar models.
