ABSTRACT

Objective To analyze the abnormal results of individual dose monitoring of some radiation workers in Chengdu from 2016 to 2018, so as to take corresponding measures to avoid similar abnormal situations. Methods The individual dose was monitored by thermoluminescence method, and the monitoring results were analyzed by spss19.0 statistical software. Results From 2016 to 2018, the number of people with abnormal dose was basically the same, and there was no significant difference in the number of people with abnormal dose in different years (P > 0.05); the number of people engaged in diagnostic radiology with abnormal personal dose accounted for 75.96%; the first reason for the abnormal personal dose was that "the personal dosimeter had been left in the radiation workplace", accounting for 92.55%. Conclusion The main reason for the abnormal results is that the dosimeter is not worn properly, so the management should be further strengthened.
