Detailed explanation-1: -The becquerel (English: /bɛkəˈrɛl/; symbol: Bq) is the unit of radioactivity in the International System of Units (SI). One becquerel is defined as the activity of a quantity of radioactive material in which one nucleus decays per second.
Detailed explanation-2: -System of Units by the becquerel (abbreviated Bq), which is exactly equal to one disintegration per second. One becquerel is a very small amount of radioactivity. For example, household smoke detectors typically contain 0.3 micrograms of the radioactive isotope americium-241, which emits about 37, 000 Bq.
Detailed explanation-3: -The SI unit for activity is one decay per second and is given the name becquerel (Bq) in honor of the discoverer of radioactivity. That is, 1Bq=1decay/s. or 3.70×1010 decays per second.
