Question: Why did you decide to do this experiment?

Why did I decide to make cells radioactive? I work on a new type of treatment for cancer that uses your own immune cells. We need to know where these cells go, to predict if they are going to be effective or harmful. I thought that using radioactivity could be a good way to understand how they behave. I hope that answers your question.
