Atomic Structure
Radioactivity
- Isotopes of some elements are radioactive. This is because they have an unstable nucleus.
- A half life is the time taken for the radioactivity of a specified isotope to fall to half its original value.
- Natural sources of background radiation: Cosmic rays, Rocks and soil, Living things
- The amount of radioactive decays happening per second is called the "activity" of a sample and is measured in Becquerels (Bq)
