While there are certificate programs in radiology available, they are typically baccalaureate certificates, designed for people who already have a college degree of some sort but wish to go into radiology. They are also attached to other degree programs, like medical assisting. If you do not have a college degree and would like to become a radiologic technologist, there are diploma and associate's degrees available at community colleges that will train you. Some schools also offer bachelor's degrees. All programs will require you to have your GED or a high school diploma.
