Interpretation: Number of decay events per second in
Concept introduction: A process through which a unstable nuclide loses its energy due to excess of protons or neutrons is known as radioactive decay. The cause of instability of a nuclide is its inefficiency in holding the nucleus together. The curie is commonly used to measure nuclear radioactivity.
