    Activity of a radioactive substance is the number of disintegration taking place in the given sample per second. The activity of a sample of radioactive nucleus equals to its decay rate (or number of nucleidecaying per unit time).
    Its SI unit is disintegration /s or becquerel.   1 Bq is one disintegration per second.
