Abstract:
Objective To investigate and analyze the cause of the abnormal results in the individual dose monitoring conducted by this laboratory from 2014 to 2017. Methods Radiologic workers wear personal thermoluminescent dosimeters to monitor the individual dose equivalent HP(10). A statistical analysis is conducted on the results above the investigation level. Results During the time when our individual dose monitoring was conducted from 2014 to 2017, this laboratory had detected 69 person-time abnormal results in 40 workplaces, of which 83% occurred in the profession of diagnostic roentgenology. 54% of the dose level range from 1.25 to 5.00 mSv. The main causes of the abnormal results include improper wearing of personal dosimeters (67%), unknown causes (20%), increased workload (10%) and equipment maintenance (3.0%)etc. Conclusion Radiation workplaces should enhance the management of radiologic workers, improve their trainings on radiation protection and raise their protection awareness.
