Would a Geiger tube detect these X-Rays? https://www.sparkfun.com/products/8875 https://www.sparkfun.com/products/8875 I'm thinking Arduino boards and webcams

  Why not just come up with a gas flow counter? That's what they do in real life rad labs.

    I've built a number of these and it would be a challenge to make a robust, portable one. Mass flow controllers are expensive and sensitive, and carrying around a supply of ethane or other gas would be inconvenient; even if cool. The detectors themselves also tend to be quite sensitive (to motion, RFI, and everything else), though much of that could probably be overcome.

  You can pick a great kit from MightyOhm that has the tube and supporting electronics to power it. It outputs data on a serial connection so it's easy to read from an Arduino. Check it out here: https://www.adafruit.com/products/483 https://www.adafruit.com/products/483 It's best for detecting gamma rays and really can't detect alpha or beta rays, so for example a smoke detector's americurium source won't really set it off but old uranium glaze cookware will drive it crazy. Not sure about x-rays but I bet it would catch them since they're pretty high energy and penetrating.

  It seems like this would do the trick: http://www.polimaster.com/products/electronic_dosimeters/pm1904a_/ http://www.polimaster.com/products/electronic_dosimeters/pm1... At least if your phone could alert you when you're being irradiated you could take note.
