Radioactive decay - the process involving
unstable
nuclei
emitting
radiation to become more
stable
Activity - the
rate
at which
nuclei
decays
Count-rate - the number of
radiation
counts
reaching a
detector
per
second
Radioactivity is measured in
Becquerels
,
Bq
Count-rate is measured using a
Geiger-Muller tube
