Fukushima Geiger Counter

In a post I wrote last year about one of our drives through Fukushima I mentioned toward the end that we met up with Koroyama resident Tadao Munakata when he was driving by and recognized the Safecast logo on someone’s shirt and stopped to talk to us. At that point he was working with some other folks to produce a geiger counter in Fukushima. Since then he’s become a regular Safecast volunteer and continued diligently working on his project. When I was just in Japan I was able to see of the results, as they’ve got two models available now. One is a standalone unit and the other has no display, and instead includes a line out and needs to connect to a smartphone running an app like Geigerbot. Both of these devices are based on the Open Geiger project and have a Russian SBM-20 Geiger Mueller tube which is sensitive to beta and gamma radiation. We’re all really excited to see this project develop and it’s great to have something like this being produced directly in Fukushima.
