Key Stage 5
Meaning
In radioactivity, activity is the number of disintegrations per second of a radioactive isotope.
About Activity
- Measured in becquerels (Bq), where 1 Bq equals one disintegration per second.
- Indicates the rate at which a sample of radioactive material decays.
- Higher activity means more frequent emissions of radiation.
