RESUMO
Objective To understand the basic information of the number, classification, and distribution of radiation work units in non-medical institutions in Shanxi Province, China, and to analyze the status quo of health management and radiation protection measures for radiation workers, so as to provide a scientific basis for occupational exposure protection in non-medical radiation work units and better protect the occupational health rights and interests of radiation workers. Methods A questionnaire survey was conducted to investigate some non-medical institutions in Shanxi Province. On-site testing was carried out to determine the risk factors for radioactive occupational diseases in the selected non-medical institutions. Results In 220 non-medical institutions, there were 340 radiation devices and 2284 radioactive sources. The rate of individual dose monitoring was 92.7% and the rate of occupational health examination was 87.2%. These devices were equipped with 325 detection instruments for radiation protection, 1316 personal protective equipment, and 730 personal dose alarms. Radiation occupational disease risk factors were investigated in 101 institutions. Conclusion The occupational health management of radiation workers in non-medical institutions in Shanxi Province is generally in line with the national standards. However, there is still a big gap with the level of occupational health management in medical institutions. The health administration departments should clarify the management measures for non-medical institutions and strengthen their supervision and management functions.
RESUMO
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.
