Chapter 38, Problem 79(choose chapter or problem)
A family member is about to have a brain scan using technetium- 99*, an excited isotope with 6.01-hour half-life. The hospital makes Tc-99* from the decay of molybdenum-99 then delivers it to the nuclear medicine department. Youre told that the Tc-99* 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-99*. Is that sufficient?
