Public exposure does not include

Public exposure refers to public exposure to radiation sources, including exposure from approved sources and practices and exposure under intervention, but excluding occupational exposure, medical exposure and local normal natural background radiation.

Contents of radiation protection management system

First, establish and improve radiation protection institutions and three-level protection responsibility system.

Two, new radiation workers, subject to health examination, can engage in radiation work, all radiation workers should have a license.

Three, personnel engaged in radiation work should wear personal dose monitors, accept personal dose monitoring, and record the monitoring results in personal dose files.

Four, radiation workers should be in accordance with the provisions of regular physical examination, the establishment of occupational health records of radiation workers.

Five, the workplace must have eye-catching warning signs of ionizing radiation, there is a red warning light above the door, and there is a safety interlock device to prevent the staff and the public from accidental exposure. Check whether all safety protection measures are in normal working condition every day.

Six, before the new radiation equipment is put into use, it is necessary to check the room area (not less than 30 square meters), room height (not less than 3.2 meters), door and window protection, staff console protection (with compartment operation), design requirements, and can be put into use only after passing the inspection.

Seven, formulate and improve the safety operation procedures, in strict accordance with the operating procedures, and inform patients and related personnel of the radiation hazards, use places posted eye-catching radiation harmful to health signs.

Eight, the development of radiation safety emergency plan, annual assessment and inspection, and constantly improve. After the accident, it should be reported in time.

Nine, in strict accordance with the radioactive quality (QA/QC) standards, maintenance engineers and physicists regularly monitor and correct the mechanical accuracy and dose of the machine.
