There are some states that don’t require a license to take X-Rays. Crazy since it is literally dangerous. I’ve lived in California and Alaska as a radiological technologist. California requires licensure, but Alaska does not. Most places that you work in the cities require it, but there are a lot of boondocks in that state and almost impossible to get techs qualified to live there. No place I have ever lived paid for my continuing education for maintaining my license.
