      H i Niamh,

      I didn’t do physics in secondary school – even though I enjoyed it up to my inter-cert.
      The physics I missed was covered during the first year in college.
      A good knowledge of physics makes understanding the processes taking place in chemistry a little easier.

    Thanks for the info! I don’t really like physics though. I just wanted to know because none of the scientists here are physicists.

      Hi dono,

      Not all radiation has bad effects. Visible light, radiowaves, microwaves and infrared light are all harmless.

      Only high energy radiation such as UV light, X rays and gamma rays can damage you.

      These types of light cause molecules to lose electrons. And sometimes when molecules lose electrons they change shape.
      And if the molecule that is involved is something like DNA then it can reproduce incorrectly and that’s when you can get cancers and deformities (if the radiation hits a growing fetus).
