👉 The concept of a Becquerel is used in physics, particularly in nuclear chemistry and radiation detection. It is defined as a unit of measurement for radioactive decay rates, typically denoted by Bq or Bq/kg. In simple terms, it is the amount of radioactivity produced per unit time when one nucleus decays into another. The term "Becquerel" was first used in 1952 by Hans Bethe and was given its modern form in 197
