Radioactive Source Strength Calculator

The strength of a radioactive source is called its activity. It is defined as the rate at which the isotope decays. The activity is the number of atoms that decay and emit radiation in one second. Given here is an online radioactive source strength calculator to calculate radiation activity and intensity given the required input values.

Calculate Radiation Activity and Intensity

Radioactivity or the strength of radioactive source is measured in units of becquerel (Bq). 1 Bq = 1 event of radiation emission or disintegration per second. One becquerel is an extremely small amount of radioactivity.
