The application of C-arm X-ray machine in surgery, whether doctors, nurses and patients are not clear about the dose of radiation exposure, and there is no means of health monitoring, which has no basis for the diagnosis and protection of radiation diseases. Therefore, it is suggested that when C-arm X-ray machine is used during operation, the relevant personnel should wear personal dose monitor to prevent the C-arm from radiating large doses of radiation to the relevant personnel. Protective goggles, neck circumference, lead coat, lead cap and lead screen are indispensable protective devices in operating room. Managers should not be bound by the concept of department cost accounting. They should take the health of personnel as the basis, provide adequate protective equipment, and ensure the correct use of relevant personnel.
