Second, the operator of such machines must be trained, usually meaning holding at least an Associate degree and unless under direct supervision, holding a certificate in diagnostic or therapeutic radiology (AART). Further, at least in states I'm familiar with, each operator may not use them until they are registered and a detailed Radiation Safety Plan is in place, with a designated Radiation Safety Officer.
