What is radiation?

Here’s the first part of an excellent talk given by Professor John McInerney, of the UCC Physics Department on what exactly radiation is, the different types, the effects they have on the human body and what creates it. Do you know where most radiation comes from? You might be surprised.

Early in the talk, John dispelled with the idea of non-ionising radiation being responsible for detrimental health effects. ”Microwaves in general are not harmful, including the ones in cell-phones and radars. Unless you cook yourself. If you stood in front of a 10KW radio antenna it would be bad for you. It would serve you right. That’s Darwin’s principle at work”.

The video was filmed at a Cork Skeptics session in Blackrock Castle last May. The second part of the talk goes into nuclear power and you can watch it above.
