Abstract Objective To investigate the risk factors of carotid arterial intima-media thickness (IMT) of intervention workers,especially for the relationship between IMT and accumulated dose of radiation. Methods 1:4 matched case-control study was carried out. The study subjects consisted of 155 intervention workers and 620 diagnostic X-ray workers coming from different hospitals in Shandong province. IMT was measured by ultrasound, meantime their accumulated dose of radiation and other risk factors were collectd. necessary analysis was applied with SPSS. Results There exists a weak positive correlation between IMT and accumulated radiation dose, age and radiation senioroty, contrarily gender shows weak negative correlation. Finally accumulated dose,age and gender remain in the linear regression equation. Conclusion Accumulated radiation dose, age may promote IMT thickening while gender the opposite.
