Question

Which of the following is an example of radiochemical impurity?

a. presence of Mo99 in Tc99m eluate
b. presence of free tech in Tc99m HDP
c. presence of Al3+ in Tc99m
d. presence of pyrogens in reconstituted kits

Answer 1

An example of a radiochemical impurity is the presence of Mo99 in Tc99m eluate, which is the resulting solution when generating Tc99m.

Step-by-step explanation:

An example of a radiochemical impurity would be the presence of Mo99 in Tc99m eluate. In the process of generating Tc99m, hospitals use Mo99 to produce it. However, some Mo99 may still be present in the Tc99m eluate, which is the resulting solution. This impurity can affect the accuracy and purity of the Tc99m used in medical procedures.
