If you don't like being bombarded with radiation I suggest you leave. You're being bombarded by radiation as you read this--the light from your screen. "Radiation", to a physicist, covers all radiated energy, all the way from the ELF radios used to communicate with submarines up to the gammas released by the targets in particle accelerators.

The popular usage of the term has been perverted into what's actually classed as ionizing radiation--stuff that's hot enough to knock electrons off everyday molecules. (I say everyday because some molecules are especially easy to knock electrons off of. All photodetectors--that includes film--and photocells are based on this.)
