A Radiation Safety Officer (RSO) is a professional responsible for ensuring the safe use of radioactive materials and radiation-producing equipment. They develop and implement safety protocols, conduct training for staff, and monitor radiation levels in facilities such as hospitals, laboratories, and nuclear power plants. The RSO plays a crucial role in protecting workers and the public from potential radiation hazards. In addition to overseeing safety measures, the RSO also ensures compliance with regulations set by organizations like the Nuclear Regulatory Commission (NRC) and Environmental Protection Agency (EPA). They investigate incidents involving radiation exposure and maintain records related to radiation safety, helping to promote a culture of safety within their organization.
