There must be a geiger counter craze going on at the moment. Following on from the geiger counter watch we reported on a few days a go you can now buy a Radiation detection device that can be attached to a set of keys, otherwise known as a keyring. The keyring chirps like a proper geiger counter (remember them from school) when radiation levels above the norm, with the frequency of chirps getting faster as radiation levels increase (though I’m not sure how you’re going to test this).
This could be classed as a multi function device:
•High radiation warning device (obviously)
•Key holder together-er device
•Lost Key Locator, needs a block of uranium (not included).
You can find more information on this at the manufacturers site, nukalert or if you want to buy one they can be purchased at ThinkGeek for the crazy price of $149.99

More than just a radiation detector, the NukAlert™ is a patented personal radiation meter, monitor and alarm. Small enough to attach to a key chain, the device operates non-stop, 24/7 and will promptly warn you of the presence of unseen, but acutely dangerous levels of radiation.
Used nationwide by federal, state and local first responders, law enforcement and the Dept. of Defense, the device is the ideal solution for increasing individual security and awareness of radiological threats. It will be very reassuring to know, with confidence, when you and your family are out of the worst danger.
