Abstract Objective To analyze the individual monitoring level and the dynamic change of interventional radiation workers for 17 medical institutions in Wuhan from 2009 to 2016 and provide a reliable basis for ensuring the health of the intervention person's health and the health administration of the administrative department of public health.Methods The monitoring method of thermoluminescence dosemitry was used based on relevant national laws and regulations and relative standards for evaluation.Results The number of intervention staff in wearing personal dosimeters was increased year. The annual dose equivalent per capita is about 0.97 mSv during 8 years, which showed a downward trend year by year; From high dose the composition ratio, the most in 2009, 27.9% and the least in 2014, 3.52%.Conclusion Interventional personnel dose of radiation workers in Wuhan is low and declining, content the requirements of national occupational exposure limits. The intervention personvel's which meets protection consciousness has gradually improved, but personnel involved in the hand external irradiation dose deserves our attention.
