How can radiation harm people?

Living tissue in the human body can be damaged by ionising radiation.  This damage can be caused either directly by the radiation damaging the genetic code (DNA) or indirectly by producing highly reactive chemicals (free radicals) which then go on to damage the DNA.  The body attempts to repair the damage, but sometimes the damage is too severe or widespread.  Cells may die if the damage is too great.
