Question
Technetium-99m (99m is mass number 99 but "meta-stable") is used in hospitals for radiation
therapies. Unfortunately, the useful form has a half-life of 6 hours which limits the ability to
transport it to remote locations. Radio-chemists developed a solution, the "Molybdenum Cow" or
moly cow, which is a laboratory apparatus that can be used to make samples of Technicium-99 in
hospital radiation labs. Every 1/2 hour or so you can wash a solution through the cow to produce a
certain amount of isotope, then you have to wait for the reaction to generate more.
Balance the Nuclear equation to determine what particle is emitted when the cow is making
Technicium-99 milk.
