Answer:
Radioactive substance decay in time and the number of atoms left over in the sample un decayed after a time t is given by the equation

,
λ
are the number of atoms in the sample initially and the decay constant. Number of radioactive disintegrations taking place in unit time is known as activity of the sample and the activity is given by the equation
