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.

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
