It is very important that a technician is licensed before he starts his career. A radiologist is licensed to make sure that he is properly trained to do the imaging and protect people from unnecessary radiation exposure. Licensing requirements varies from one country to other however most of them are certified by the American Registry of Radiologic Technologist (ARRT). In order to become certified by the AART the technicians must graduate from a college that offers the accredited radiology program and clear the exams conducted by the organization.

Other radiation technology requirements include patience and good communication skills. The technician must also take necessary steps to protect their patients from the radiation. The radiologist must wear lead aprons to avoid direct radiation to pass through the skin. They also provide the patients with these lead aprons and other sheets to prevent exposure to radiation. Sometimes the patients may be emotional; it is the duty of the radiologist to convince them for the imagery.
