The specific isotopes used depends on the particular organ or body system being studied (for example, Xe-133 is used to image lung function and blood flow.) Technetium-99m is a common radioactive isotope using for a variety of medical applications. It is produced from the decay of Molybdenum-99 and has a half-life of 6.01 hours. What are some of the applications of Tc-99m? While harder to access, another radioactive isotope of technetium, Tc-93, has a half-life of 2.73 hours. If it were easier to harvest, would this be a good substitute for Tc-99m? (remember to explain why for full credit) While Tc-99m has a half-life of 6.01 hours, its decay product has a half-life of 213,000 years.
