Final answer:
The eluate containing TcO4 and Mo99 is within the standards of radionuclidic purity set forth by the NRC.
Step-by-step explanation:
The question asks whether the eluate, containing 450 mCi of TcO4 with 200 uCi Mo99, is within the standards of radionuclidic purity set forth by the NRC. To determine this, we need to compare the amount of impurity (Mo99) to the total activity (TcO4). The NRC sets a limit of 0.15% for radiochemical impurity, so if the Mo99 content is less than 0.15% of the total activity, it would be within the standards. Let's calculate:
Total activity = 450 mCi = 450,000 uCi
Impurity content = 200 uCi
Impurity % = (Impurity content / Total activity) * 100
Impurity % = (200 / 450000) * 100 = 0.0444%
Since the impurity % is less than the NRC limit of 0.15%, the eluate is within the standards of radionuclidic purity set forth by the NRC. Therefore, the answer is a. yes.
