You are hereradiation
I attended the second DIY geiger counter workshop on August 22. This was taught by Kalin, and involved soldering three parts of a homemade gieger counter:
- Freakduino motherboard (right) - this is basically an arduino board with a wireless radio interface. It provides the power to the NetRAD and keeps track of the rate of radioactive events.
- NetRAD shield (left) - an interface to power the tube and keep a TCP/IP connection for communication.
The 2nd-in-a-row class will be held at THS house, as usual on August 22nd, 19:30-22:30: http://www.tokyohackerspace.org/en/book/how-to-get-there
See this for more insights on the history of this kit:
This kit is a THS project in collaboration with SafeCast. Once you buy and build your device, you own it (hardware and software) and the data it produces. You can opt-in to have your data logged to the THS account on Pachube (for free) and have it available to the public (for free).
I am planing to organize a DIY GM counter workshop. Details are still not fixed, stay tuned.

The kit consist of 3 parts: motherboard (Freakduino), daugtherboard (NetRAD shield) and radiation sensor (SBM-20 GM tube). If you have any of these, you can use yours, but we'll have to make sure they are similar enough.
Pieter and I went to MIT Media Lab to attend the Safecast meetup and discuss the radiation mapping project. Along with meeting everyone involved in Safecast on the US side, we got the chance to hang out at the High/Low Tech lab with Leah Buechley. Leah was the designer of the LilyPad Arduino and also works on craft-oriented applications of technology. I was struck by the similarities of hearing her talk and listening to Mitch Altman talk. One of the other things I was impressed with is that the supply jars in the High/Low tech lab don't have the usual things like screws or parts.
This is the project page for the Tokyo Hackerspace/RDTN Geiger project. This is an Arduino-based geiger counter shield that makes it easy to upload data to the internet and also interchange tubes. Since it's open source and Arduino-based, its also easy to hack this to other interesting applications.
Here's the dev history:

Lets get to work!
Meet up, discuss future plans, build solar lantern kits, hack together prototypes, and set up short hop wifi networks.
Research geiger counter circuitry, whatever.
