When using a Mo-99/Tc-99m generator for the production of technetium-99m,

Question

Quizplus · Accepted Answer

A) The eluate extracted from the Mo-99/Tc-99m generator is in the form of sodium pertechnetate (Na99mTcO4).
B) The maximum activity of Tc-99m occurs after 4 half-lives as this is the point when the activity of Tc-99m reaches its equilibrium with the parent Mo-99.
C) The maximum activity of Tc-99m occurs approximately 24 hours after the generator is eluted as Tc-99m has a half-life of 6 hours and takes approximately 4 half-lives to reach equilibrium.
