How to Turn a Compact Camera into a Radiation Detector

Andrew Lathrop came up with this novel way of building a simple radiation detector using an old compact camera, plastic scintillators, some reflective material, and black tape. A scintillator is material that lights up when exposed to radiation, and might be a little difficult for you to get your hands on unless you work in a science lab. Lathrop sent his idea to newspapers in Japan after the recent earthquake, but none of them decided to publish it.
