A clinical scientist monitors a radioactive sample of a medical isotope with a half-life of 6 hours.
Initially, at t=0t = 0t=0, the sample has an activity of 160 kilobecquerels (kBq).
Complete the graph on Figure 1 as accurately as possible to show how the activity of this isotope changes over a 24-hour period.
The first point at t=0t = 0t=0 is already plotted for you on Figure 1.
