What type of training is required before working with radiographic sources?

Initial radiation safety and operational training is essential for individuals working with radiographic sources because it provides crucial knowledge on the hazards associated with ionizing radiation, effective safety practices, and the proper operation of radiographic equipment. This training ensures that personnel understand radiation principles, protective measures to minimize exposure, and emergency procedures in case of incidents. It forms a foundational base that helps maintain safety for both the operators and surrounding individuals in environments where radiographic activities occur.

In contrast, relying solely on hands-on training would not cover the critical theoretical aspects of radiation safety and could leave personnel unprepared for situations that require understanding beyond practical skills. No training being necessary is a serious oversight, as it endangers not just the workers but also others in the vicinity. General safety training might cover broader safety topics but would lack the specific focus on radiation safety essential for handling radiographic sources effectively.
