Prototype of an ionisation chamber-based radiation detector for OpenRelief. Designed around a Nanode but could easily make use of another Arduino-compatible board with Ethernet.

Note that this design/code is alpha quality. Known issues include:

• Code ceases to print measurements out to the serial port if Ethernet is not connected
• No scaling in code
• Chamber design needs optimising, e.g. tweaking its capacitance
• Prototype makes use of 3 x 9v (PP3) batteries for chamber bias, and this needs replacing with an Arduino shield boost converter
