|
All of these

Explanation:
Detailed explanation-1: -The SI unit of radioactivity is becquerel (Bq) and this term is named after Henri Becquerel. Unit of radioactivity is defined as: The activity of a quantity of radioactive material where one decay takes place per second.
Detailed explanation-2: -The SI unit of radioactivity is the Becquerel (Bq)-equivalent to an average disintegration rate of one per second.
Detailed explanation-3: -The rutherford (symbol Rd) is a non-SI unit of radioactive decay. It is defined as the activity of a quantity of radioactive material in which one million nuclei decay per second. It is therefore equivalent to one megabecquerel, and one becquerel equals one microrutherford.
