Physical Danger

This is an intellectual and creative thinking job, but you won't become a long-fingered geek sitting in the dark eating Hot Pockets and chugging Pepsi One. Your body could be the target of stress-related illnesses if you don't practice what you preach.

And then there's the radiation. You are working in nuclear medicine, for goodness sakes. In reality, highly trained technicians and assistants will be doing the button-pushing on the X-rays, MRIs, CT and PET scans, but medical students always wonder: Is it safe to be around radiation for the rest of my career?

Fortunately, the answer is yes.
