Can A Lpn Work In The Radiology Department?

I was wondering if they allow LPNs in the radiology department to work? And if they do allow this could they train the LPN to become an Radiology Tech?

Can you tell me radiology career ladder?

Make sure includes radiologic technologist because I am planning to write about radiologic technologist. Examples Career ladder of nurse: Registered Nurse (RN) >> Licensed Practical Nurse (LPN) >> Certified Nurse Assistant (CNA)
