  A Cheaper option is to take a selected photodiode, or power transistor, shield it from light, amplify, detect and display and you have a very low-cost alpha, beta, and gamma RAD display.   

Elektor has published an excellent series of articles on this and sells a kit and I have a commercial cell/sat-based solution to sensing RAD on a mobile asset.  APRS is a GREAT emergency backup to sensing radiation! 

 I will post links if interested.  Also look at the 1,000's of RAD sensors on the COSM network and see what the Japanese engineers have done as a response to the nuclear disaster. What we learned from this crisis is not to trust you government!
