Question 14

Easy

Sodium-24 is a radioactive isotope used as a tracer in medicine. It has a half-life of 15 hours.

An administrative error meant a sample was left in a clinic. The activity of the sodium-24 sample was found to have decreased from $Bq320\text{ Bq}$ to $Bq10\text{ Bq}$ .

Determine the time, in hours, that passed between these two measurements.
