Question 1

A sample of I-131 decays from 12 microcuries to 3.0 microcuries in 16 days. What is the half-life of I-131?
◦ 32 days
◦ 8.0 days
◦ 16 days
◦ 4.0 days
◦ 64 days

Question 2

Why is it important that radioisotopes used in diagnostic tests have short half-lives?
◦ These radioisotopes have a greater activity so they are easier to monitor.
◦ This minimizes the harmful side effects of the radiation.
◦ These radioisotopes are more abundant in nature.
◦ These radioisotopes are less expensive.
◦ This is necessary so the radioisotopes will have high energy.
