What is the maximum amount of aluminum breakthrough from Tc99m generator eluate allowed by the NRC?

Answer 1

The maximum amount of aluminum breakthrough allowed by the NRC in Tc99m generator eluate is less than 10 µg/mL.

Step-by-step explanation:

The maximum amount of aluminum breakthrough from a Tc99m generator eluate allowed by the NRC is typically less than 10 micrograms per milliliter (µg/mL).

This limit is set to ensure the radiochemical purity of the Tc99m eluate, which refers to the percentage of Tc99m present in the eluate and the absence of other impurities, such as aluminum.

Exceeding this limit can affect the quality and accuracy of medical imaging studies using Tc99m.
