We got inquires from Shigeru in Tokyo about Geiger Mueller Tube, as the nuclear accident in FUKUSHIMA is escalating.

Can open hardware community do something to help in this? Seeed Studio is now sourcing sensors, then assemble quick measurement tools,  ship as many/fast as possible to Japan.

Since we have no previous experience with such device,  your help is needed!

If you have experience in making such device, some quick questions:

1. What would be the right sensor for such detection? Will the education purpose GM tube work?

2. Any recommended peripheral circuits?

3. Does such Geiger counter needs special calibration? Or can we calibrate it with commercial device?

All creations will be open source and donated, thank you for helping out!
