BRAINCAKEThe Dangers of Radioactivity
Ionising radiation such as u.v., X-rays, gamma rays and alpha and beta particles, damages living cells by damaging membranes, damaging DNA, creating free radicals which react with vital molecules. If DNA is damaged, cells may divide uncontrollably causing potentially cancerous tumours. If the mutation is in a sex cell, the mutation will be passed on to many generations.
