Following up on my earlier post on Radiation Charts - I've discovered two more (via Infosthetics).
1. A Radiation Levels chart translated from Japanese to English by Michael Gakuran
2. An interactive Anual Radiation Dose "chart" (more of a web-form) from the American Nuclear Society that allows you to estimate your annual radiation dosage. Mine is just over 4 milliSieverts per annum.
