Safecasting Koriyama & Chiba

As you may have seen in the video we posted the other day we were looking into a hotspot in Chiba and some of the contamination there. We have a SAM 940 Radiation Isotope Identifier and some filters for our geiger counters so we’re able to do a little deeper investigation at times. What we…

Safecast Drives as of May 29

The team at Keio University’s ‘Scanning The Earth’ project as plotted every single data point that we’ve collected on our mobile drives onto one single map. They have close up and zoomed out JPGs of the entire thing, as well as a Google Earth KMZ file that you can download and explore on your own…

Safecasting Aizu

On May 22nd, Safecast teammembers Hiroshi Yoshino and Pieter Franken drove to Aizu with bGeigies to measure the radiation levels. The measurements recorded were overall low which is great news for the residents of the area. Our team met up with some of the mother organized volunteer groups that are forming to help protect children…

bGeigie Ninja, a new and improved bGeigie

The original bGeigie design dictated that a self contained radiation sensor would be attached to a laptop and a GPS device and data would be logged and recorded through that. This system worked but required a lot of hardware. At Tokyo Hackerspace, Akiba has been working on his own sensor board design for his company…

Radiation Measurement Experiment

Here is a little video of Safecast team members Kalin Kozhuharov and Pieter Franken in Ichikawa, Chiba Prefecture demonstrating some radiation measurement and filtering methods we’re using in Japan. The video is about 20 minutes but runs through many examples to give a clear idea how it all works. 私達が日本で採用している放射線測定方法とフィルタリング方法のいくつかを、SafecastのチームメンバーであるKalin KozhuharovとPieter Frankenが千葉県市川市内で説明している短いビデオをここに掲載します。ビデオは約20分ですが、これらの方法がどのように機能するかを多数の例を挙げながら説明しています。

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…
