  3. Are humans able to see gamma rays? Can other organisms see gamma rays? • Humans are not able to see gamma rays without a special technological device. • The gamma log is a human made detector that allows people to see gamma rays. • No organisms can see gamma rays.

  4. Can gamma rays hurt humans and how? • Yes. When gamma ray molecules collide with a molecule in your body it can damage or destroy it. • If this happens it can lead to cancer.
