The activity of the source in Becquerel is 333.3Bq

What is Activity ?

The number of nuclei that disintegrate or decay per unit time is known as Activity.

Given that a sample of radioactive material emits 400000 particles over a period of 20 minutes.

  • N = 400000 particles
  • t = 20 min = 20 x 60 = 1200 s

Activity A = dN/dt

A = 400000 / 1200

A = 333.3 particles / s

A = 333.3 Bq

Therefore,
