Abstract:
Objective To analyze the relevant measures of radiation protection for dental X-ray diagnostic projects in 44 dental clinics in Guangdong Province, China, and discuss common problems. Methods Based on the three principles of radiation protection, relevant laws, regulations and standards of the state, combined with field investigations and test results of radiation protection, the situation of radiation protection and management was analyzed. Results The layout of 56 dental diagnostic rooms in 44 clinics was (basically) reasonable. The protective performances and quality control tests of 56 dental X-ray diagnostic machines met the standard requirements, and the dose equivalent rate around 56 dental diagnostic rooms was from the background to 1.47 μSv/h, which met the national standard. The coincidence rates of ionizing radiation warning signs, working status indicator lights and door light interlocks, automatic door closing devices, power ventilation devices, and personal protective equipment were from 85.70% to 98.20%. The compliance rates of dental radiologists and full-time (part-time) administrative staffs, occupational health monitoring, management system related to radiation protection, and radiation health files were from 79.5% to 100.0%. Conclusion The current situation of radiation protection and management in the dental X-ray diagnostic room is good, and relevant national regulations and standards should be promulgated or improved to standardize the cone-beam CT quality control testing, dental clinic location requirements, and radiation staff configuration.
