SparkX sold out! But we now have this available through SparkFun over here.
The PocketGeiger-Type5 from Radiation Watch is a highly sensitive radiation sensor designed for the embedded systems market. Capable of detecting Gamma and Beta radiation, it has a simple pulsed output that can be used with any microcontroller. The Pocket Geiger has an onboard DC boost circuit, so the board can be supplied with a friendly 3V to 9V. Using only 30mW (10mA @ 3V), it is very low power. Radiation Watch has a handful of documents and example Arduino code to get you up and running. They have also written a Windows example program written in C# (source included!) to output graphs to a computer using an Arduino as the reader. Additionally, the counter comes with an optional enclosure and 3.5mm cable that allow you to connect the counter to some mobile phones (may not be compatible with phones sold in the EU).
We do not plan to regularly carry SparkX products so get them while they're hot!
Required Measurement Time: 2min

I was able to get this up and running with the included Arduino sketch within minutes.
It does take a about 2 and half minutes to start reporting even the baseline radioactivity.
I love the trefoil that comes on the box. Having a case to go with it is very convenient. Overall it's one of my cooler sensor purchases.
Planning on generating some random numbers with this entropy.
