A professional who tests x-ray equipment, inspects areas where equipment is used, and evaluates operating procedures to detect and control radiation hazards. Responsibilities include:

• Visits hospitals, medical offices, and other establishments to test x-ray machines and fluoroscopes and to inspect premises.
• Tests equipment to determine that kilovolt potential, alignment of components, and other elements of equipment meet standards for safe operation, using specialized instruments and procedures.
• Operates equipment to determine need for calibration, repair, or replacement of tubes or other parts.
• Measures density of lead shielding in walls, using radiometric equipment.
• Computes cumulative radiation levels and refers to regulations to determine if amount of shielding is sufficient to absorb radiation emissions.
• Examines license of equipment operator for authenticity and observes operating practices to determine competence of operator to use equipment.
• Confers with physicians, dentists, and x-ray personnel to explain procedures and legal requirements pertaining to use of equipment.
• Demonstrates exposure techniques to improve procedures and minimize amount of radiation delivered to patient and operator.
• Reviews plans and specifications for proposed x-ray installations for conformance to legal requirements and radiation safety practices.
• Contacts organizations submitting inadequate specifications to explain changes in shielding or layout needed to conform to regulations.
