Meaning
Irradiation is when a material is exposed to ionising radiation.
About Irradiation
- Irradiation is dangerous because it can cause the atoms in living tissue to become ionised which can kill cells or damage their DNA leading to cancer.
- Irradiation can be useful as it can destroy living organisms such as bacteria. Food and medical equipment are irradiated to sterilise them.
- Irradiation does not leave a material radioactive so after a material has been irradiated the danger is gone.
