Question 2 · 1 mark · Difficulty 1/3

What is meant by the 'activity' of a radioactive source?

  1. The number of nuclear decays per second in the source
  2. The time taken for half the atoms to decay
  3. The energy released by the source each second
  4. The number of radioactive atoms present in the source
Show answer & explanation
✓ Answer: AThe number of nuclear decays per second in the source
Activity is defined as the number of nuclear decays (disintegrations) per second, measured in becquerels (Bq). Option A describes the count of atoms, not the rate of decay. Option C describes power output, which is not activity. Option D is the definition of half-life, a related but distinct concept.
