How many nuclear transformations per second does one Becquerel correspond to?

One Becquerel is defined as one nuclear transformation occurring per second. This unit of measurement indicates the rate at which a radioactive substance undergoes decay or transformation—essentially quantifying the amount of radioactive activity. Therefore, if a substance has a radioactivity of one Becquerel, it means that one nucleus of that substance is disintegrating every second.

Understanding this concept is essential in fields such as medical dosimetry, where accurate measurements of radioactive decay rates are crucial for calculations regarding treatment planning and dosimetry in radiotherapy. The clarity of this definition helps to ensure proper safety protocols and accurate delivery of radiation doses in clinical settings.
