Safecasting with Keio University

As you may recall we’ve been working with a team from Keio University and recently equipped them with one of our bGeigie mobile sensor units. Over several days they drove through Fukushima, Iitate and Minami-soma documenting the radiation levels and taking photos of some of the destruction and neighborhoods. The map of those radiation readings…

Safecasting Iwaki

As you know, over the last few weeks our team of Tokyo based volunteers have been taking regular trips north with mobile bGeigie rigs to monitor and record radiation data. We wanted to show more behind the scenes from those trips, so here’s a few photos from a recent trip through Iwaki, Fukushima. Above: Safecast…

Making of the bGeigie

Last month I talked about a device we’ve been lovingly referring to as the bGeigie. We concepted it out for the first mobile run and then replicated it for a series of runs last week. The “b” stands for “Bento” and since we’re building these units into cute little boxes we thought that was fitting.…

Volunteer field report: Kiki

[Kiki Tanaka reached out to us and offered to help take readings. We set her up with a geiger counter and some instructions and asked that she report back what she found. This is the the first report from her.] May 8th, 2011 I am Kiki Tanaka. I am not a technical person, so I…

New survey suggests current evacuation zones flawed

A new joint survey by the US and Japan shows that evacuations based on distance from the plant is not the best approach. This confirms suspicions that wind carried radioactive particles to the northwest and many areas beyond the current evacuation zone are showing elevated levels, as well as some areas to the southwest that…

A radiation dose survey map via probe cars in Fukushima

[As part of our mission, we’ve been giving equipment to outside volunteers with the understanding they will take readings and report back. We gave one of our mobile bGeigie units to a team from Keio University. This is a guest post written by Tomoyuki Furutani of Keio University about their findings.] Keio team conducted a…

bGeigie in motion – mobile radiation readings

Last month I blogged about our concept bGeigie, which is essentially a pair of geiger counters rigged to a car and connected to a GPS device and laptop to log the points as we drive around the country side. We’ve now completed several of these drives and have mapped out the data so it makes…

Alpha, Beta, Gamma

The sensors we’re using are very sensitive and pick up Apha, Beta and Gamma radiation which is different for some equipment and published readings which sometimes eliminate Alpha all together, or focus specifically on high energy Gamma. We’ve created some filters that block different kinds of radiation so we can break down our measurements and…
