Google gives me around 2 million hits for "electromagnetic radiation".
Google gives me around 275,000 hits for 'Bill Gates is Satan' and 130,000 hits for 'Every time you masterbate, a kitten dies' but I can't vouch for the latter.
That's especially shocking given that you spelled masturbate wrong ;-)
Hey I wasn't using google to establish the truth-value of a proposition. I was just trying to show that there's wide-scale usage of 'radiation' to describe what an electromagnetic wave is.
