These are a few of my favourite links!!
There are several pages and I am hard pressed to know which to put first.
This is a link to a very helpful fact sheet on the absolute, simplest basics of nuclear radiation and health. Radiation Basics: The what, why and how of radiation damage, March 2010 from Beyond Nuclear and found below.
Beyond Nuclear aims to educate and activate the public about the connections between nuclear power and nuclear weapons and the need to abandon both to safeguard our future. Beyond Nuclear advocates for an energy future that is sustainable, benign and democratic.
