After the Fukushima Daiichi nuclear disaster all the geiger counter to measure the radiation levels sold out. The group Safecast was started to build geiger counter and collect data of the radiation levels in Japan. They saw a huge need of this data and also started to to collect data from other places around the world.
We meet the group Safecast in Tokyo and followed them to Akihabara Electric Town to find components to build geiger counter and also did a car drive to collect and see radiation levels in Tokyo city.
We also visited Tokyo Hackerspace to see what they was up to.
