How does the job of a nuclear pharmacist relate to chemistry?

I'm doing a project for school and I can't really find anything on how it relates to chemistry. Obviously, the job relates, I just can't really figure out how to word it or how to explain it.

most of the nucleotides are used in nuclear medicine and have very short half lifes. Because you first have to create the nuclear elements with the help of an accelerator, a certain amount of chemistry is necessary to incorporate these isotopes in a compound that can be introduced into the human body for imaging.

I would suggest you start your reseach by reviewing nuclear medicine and and radiation oncology as starting points in wikipedia.

There is a whole subsection to chemistry called nuclear chemistry or radiochemistry. It is different than classical chemistry because it involves transformations of the nucleus, not the electrons. Even with the differences, though, radiochemistry studies similar processes; how do you analyze radio chemicals, how do you separate them, how much do you need for a therapeutic dose, etc. These are very important to both nuclear medicine and chemistry.

Nuclear pharmacy requires a knowledge of chemistry in order to understand how to produce the drugs that will be used, what there structures, components and chemical properties are. Also chemistry teaches the advanced lab techniques required to produce the medicine which must be done on site.

This is just a quick answer but hope it helps
