Abstract Objective Analysis and evaluation of occupational exposure dose for workers in PET/CT radiology departments of Fujian.Methods According to the monitoring results of ambient dose equivalent rate and personal dose equivalent of radiation works around 5 PET/CT workplaces in Fujian from 2014 to 2016, The occupational exposure doses of PET/CT radiation workers were analyzed and compared with the national standard dose limit.Results The average annual individual effective dose of radiation workers was 0.50 mSv, and the annual effective dose of all radiation workers was less than 5 mSv. Without personal protection measures, the estimated annual maximum radiation doses for hand, head, neck and chest positions of radiation workers engaged in radiopharmaceuticals, injection and PET/CT co-room positioning were 549.0, 137.4 and 134.0 mSv, respectively.Conclusion Under the normal working conditions, the occupational exposure dose of radiation workers is at a low level, which meets the relevant requirements. Without effective personal protective measures, the occupational exposure dose of radiation workers will exceed the national standard on occupational exposure limit.
