Abstract Objective Analyze the anomaly causes of Individual monitoring data of radiation workers and propose corresponding measures.Methods For persons whose monitoring results exceeded the investigation level for a single personal dose monitoring, a magnified dose questionnaire will be issued, requesting the signature of the person monitored, sign of the person in charge of the department, and official seal of the unit.Results Of the 3 804 individual monitoring visits in Zhejiang Province in 2018, 21 were abnormal, accounting for 0.55%. The maximum dose is 14.88 mSv and the minimum dose is 1.264 mSv.Conclusion The abnormal results are not actual, mainly caused by poor management of personal dose gauge by radiation workers.The key measures to solve the problem are to strengthen the publicity of the legal system and radiation protection knowledge, strengthen the protection consciousness of the grass-roots radiation workers, and wear dosimeters correctly.
