How often must radiographic equipment be tested for leakage radiation?

Radiographic equipment must be tested for leakage radiation annually or as specified by applicable regulations to ensure that the equipment is functioning safely and within the acceptable limits for radiation exposure. Regular testing is crucial because it helps identify any potential issues with the integrity of the shielding and containment of the radioactive sources used in industrial radiography. This proactive approach ensures that any unnecessary or harmful radiation exposure to personnel or the public is minimized, thereby maintaining safety standards and compliance with regulatory guidelines. By adhering to this practice, operators can detect and resolve issues promptly, ensuring the equipment's reliability and the safety of the surrounding environment.
