It is always interesting to see how people handle a word like 'radiation' as if it's all that one big bad dangerous type. People, please, read up on the physics before you start to worry too much. Radiation is many things, but the word itself is used in media to scare people (and thus make them listen to whatever they have to say) - because that word have negative feel in our society since the world wars. I'm not saying that there might not be anything to the statements (I don't have the data), but just don't fall for the word hypes, please.
