Which of the following is NOT a role of the radiological safety officer (RSO)?

The role of the radiological safety officer (RSO) primarily involves responsibilities related to health, safety, and regulatory compliance in the use of radioactive materials and equipment. Training personnel is essential for ensuring that everyone involved understands safe practices and the proper handling of radiological equipment. Ensuring compliance with regulations is critical, as the RSO must make sure that the organization adheres to local, state, and federal laws related to radioactive materials. Overseeing safety protocols is a fundamental part of the RSO's job, as they are responsible for implementing and monitoring procedures that protect staff and the environment from radiation exposure.

In contrast, marketing the gauge products does not fall within the scope of the RSO’s responsibilities. This task is typically handled by marketing or sales departments, whose focus is on promoting and selling products rather than ensuring safety and compliance regarding their use.
