Submission + - Japanese can build their own radiation detectors ( 1

EmperorOfCanada writes: "Here is a DIY radiation detector For those Japanese wondering if radiation levels have gone up that can be made with household supplies: any clear sided container with a flat metal(preferably) lid, some black paint, rubbing alcohol, a can of keyboard air duster, and a flashlight . This won't give an absolute measurement but it will tell you if you are in a hot zone. The radiation leaves trails in the mist and looks very cool. Can't beat a home made Geiger counter in 10 minutes and for less than $20 US."
