Question 16

Easy

Figure 1 shows a graph representing how the activity of a sample of iodine-131 changes over time.

Graph showing the decay of iodine-131 activity over 32 days. The vertical y-axis is labeled 'Activity (MBq)' and goes from 0 to 100 in steps of 10. The horizontal x-axis is labeled 'Time (days)' and goes from 0 to 32 in steps of 4. The curve starts at 80 MBq at time = 0. It passes through (8, 40), (16, 20), and (24, 10).

Use Figure 1 to estimate the half-life of iodine-131.
