Pecker Wrecker?

Since getting a notebook a little while ago I have been using it on my lap a lot and it got me to thinking, am I frying my old fella with radiation. A little googling hasn't found an obvious answer.

I did find something from 2002 talking about Levis introducing jeans with an anti radiation lead lined pocket for your mobile phone..lol and this comment which made me piss myself laughing (fortunately not while my laptop was actually on my lap) :-

"I'd definitely buy pants that protected me from nuclear war. It'd be an easy sell too."

"You like nuclear war?"

"Uh, no, not much."

"Well, I got pants what prevent that. Pants against nuclear war, see?"

"Gimme."
