The graph shows how the activity of a sample of Phosphorus-32, used in clinical radiotherapy to treat bone and blood disorders, varies with time.
Determine the time required for the activity of this sample of Phosphorus-32 to fall to half of its initial activity.
State the half-life of Phosphorus-32.
