Radiation hygiene management status of 35 non-medical institutions in Tianjin

Objective To understand the current status of radiation hygiene management in non-medical institutions in Tianjin to provide scientific basis for strengthening health management in the radiological department. Methods A cross-sectional questionnaire survey was conducted from August to October 2020 according to the Notice of Municipal Health Commission on the implementation plan of the Tianjin occupation disease prevention and control project in 2020, to evaluate 35 non-medical institutions in Tianjin according to the industry category of monitoring objects, the basic situation of radiation source, occupation health management, personal protective equipment, and auxiliary protective devices. Data were entered by double input method and analyzed. Results The survey covered 11 industries including computers, telecommunications, and other electronic equipment manufacturing; port handling and storage; metal products; and petroleum and natural gas extraction. The survey includes 91 class Ⅱ and 84 class Ⅲ radiation devices; 53 class Ⅱ, 7 class Ⅲ, 88 class Ⅳ, and 253 class Ⅴ radiation sources; 4 unsealed radioactive material class B workplace; and 2 unsealed radioactive material class C workplace. A total of 921 radiation workers in the 35 radiological non-medical institutions underwent occupation health examination, and the annual effective dose of radiation workers was lower than 20 mSv. The 35 institutions were equipped with 274 personal protective equipment, 194 personal dose alarming devices, and 135 radiation dosimeter. Twenty-nine non-medical institutions (82.9%, 29/35) carried out occupation health assessment and self-inspection, and 34 non-medical institutions (97.1%, 34/35) completed the radiation protection test. The rate of institutions that qualified in the radiation protection test and the declaration of occupational hazard items were both 85.7% (30/35). Conclusions The 35 non-medical institutions could take radiation hygiene protection management seriously. This study provides a scientific basis for the supervision and law enforcement of related policies. Nevertheless, strengthening the implementation of personal protective equipment and radiation dosimetry, as well as occupation disease risk monitoring and evaluation, is necessary.
