A Radiation Safety Officer (RSO) is a professional responsible for ensuring the safe use of radiation in various settings, such as hospitals, research facilities, and nuclear power plants. They develop and implement safety protocols to protect workers, patients, and the public from harmful exposure to radiation. RSOs also conduct regular inspections and training sessions to maintain compliance with safety regulations. In addition to monitoring radiation levels, RSOs are involved in emergency response planning and incident investigation. They work closely with regulatory agencies, such as the Nuclear Regulatory Commission, to ensure that all practices meet legal and safety standards. Their role is crucial in promoting a safe environment where radiation is used responsibly.
