A family member is about to have a brain scan using technetium-99m, an excited isotope
Chapter 38, Problem 81(choose chapter or problem)
A family member is about to have a brain scan using technetium-99m, an excited isotope with 6.01-hour half-life. The hospital makes Tc-99m from the decay of molybdenum-99 1t1/2 = 2.7 days2, then delivers it to the nuclear medicine department. Youre told that the Tc-99m will arrive 90 minutes after production, and that there must be 10 mg of it. The technician says she will produce 12 mg of Tc-99m. Is that sufficient?
