Charles Pope a well know expert on Non-destructive radiation expels a few myths surrounding the fears associated with the use of radiation. Charles is what you would discribe, a Nuclear Greenie. He has written a layman's guide in plain English to ionising radiation over the last 4 billion years via prehistoric Gabon, Einstein, Hiroshima, Chernobyl and Fukushima. We really do stress ourselves too much about nuclear radiation simply because we don't understand it. In the process we forfeit our best get-out-of-jail card for base load carbon-free energy until the hoped-for renewables can fill the gap. Charles Pope is a nuclear environmentalist and has used radioactive materials and X-ray equipment for his working life and trained others in their safe use. He is more convinced by arithmetic than emotion. It's time to stop shouting slogans and start understanding the manageable risks of nuclear energy.
