Essentially, this top expert in the field says that radioactivity is not dangerous in general. He says that he used to swim in the radioactive pools at nuke plants he designed and would eat radioactive material repeatedly on his lecture tours. This is no mere scientific layman, but the engineer who designed some of the first nuclear power plants.
Interesting. It doesn't mean he never suffered effects from it years later. He admits the radiation exists, that it can do things that are harmful to the body (generating UV when reacting with the air), and that it can cause burns and death in high amounts. He seems focused on the immediate effects: visible burns and death, and doesn't seem to consider any long term effects even after the body has initially healed from a burn. He may be wrong on radiation, I think he is. I've only ever been concerned about the long term effects like with sunburns, not the immediate risk of handling radioactive and other toxic metals (lead). It doesn't mean he's wrong about the conspiracy stuff, and yes, the lawmakers are lying by saying you will get burned when you won't.
