40. Tc-99 is often used as a radioactive tracer in several medical diagnostic procedures. It has radioactive half-life of 6 hours. Because of its short half-life, it does not stay in the patient's body for a long time, and thus is vey suitable for diagnostic, but not treatment, purposes. On July 20, 2020 at 6:00 AM, a patient is given 64.0 ug (micrograms) of Tc-99. Assume that no process (but for the radioactive decay) depletes the isotope from the patient's body. other a. How much of Tc-99 will remain in the patient's body after 24 hours (i.e., 6:00 AM July 21, 2020)? b. When (Date/Time) will there be about 1.0 microgram of the isotope left in the patient's body?

You are working as a technician in the radiology department of a large hospital. One of the radioactive isotopes that is used to treat cancer is 60Co. Although use of this isotope is decreasing due to the availability of electrons from linear accelerators, 60Co is still in wide use where accelerators are not available. A radiologist has asked you to supply a container of 60Co, and you need to determine if a particular sample. on the supply shelf is still viable for use. During your training, you learned that cobalt is not viable for medical use if its activity has fallen to 60.0% of its activity when delivered to the hospital. The label on the sample states that the delivery date was January 31, over three-and-a-half years ago. It is now December 31. Should you send this sample to the radiologist, or should it be disposed of? (60Co has a half-life of 5.27 yr.)
Technetium-99m is an important isotope used in medical imaging (the m stands for metastable). Each day healthcare professionals around the world use Technetium-99m in thousands of medical scans. This material has a very short half-life of about 6 hours and decays by gamma decay to Technetium-99. look at why half-life is an important concern and how it affects your health. 1. Technetium-99m has a half-life of 6 hours. Use this to answer the following questions: a. What percentage of Technituum-99m would remain in your body 24 hours after injection with this radioisotope? Assume that the initial percentage is 100%.
