ABSTRACT
@#<b>Objective</b> To investigate the number and categorical distribution of non-medical radiation institutions in Fujian Province, China, and to explore the current situation of radiation occupational hazards prevention and control and the occupational health management of radiation workers in employing units. <b>Methods</b> The industrial enterprises engaged in the application of nuclear technology in our province were investigated, and different types of employing units were selected to monitor the radioactivity level in the workplace. <b>Results</b> A total of 377 non-medical radiation institutions were reported in the province, with a total of 5221 radiation workers (except luggage detector units); 1246 radiation workers held radiation worker certificates, accounting for 23.87%; 5103 radiation workers carried out personal dose monitoring, accounting for 97.74%; 5061 radiation workers participated in radiation protection knowledge training, accounting for 96.94%; a total of 4895 (93.76%)radiation workers received physical examination. <b>Conclusion</b> Health supervision authorities in Fujian Province should strengthen the supervision of non-medical radiation institutions, further improve the level of occupational health management, and protect the health rights and interests of radiation workers to the maximum extent.
ABSTRACT
Objective:To ascertain the basic situation of radiotherapy in Fujian in 2016.Methods:Based on the unified questionnaire, the types and quantity of radiotherapy and its corollary equipment, the number of radiotherapy staff and the work for quality control were surveyed in the radiotherapy units in the whole province, and the data on patients undergoing radiotherapy and other types of patients were collected from 26 hospitals. The total number of radiotherapy patients in the whole province was estimated by the correlation analysis and multiple linear regression analysis.Results:Radiotherapy was performed in a total of 32 hospitals in Fujian province in 2016. Among them, there were 62 sets of radiotherapy equipment, 33 sets of the simulators, 57 sets of treatment planning systems and 762 workers. The total number of 15 156 radiotherapy patients in 26 hospital were available for the survey. Multiple linear regression models showed that the frequency of application of medical electron accelerator was positively correlated with number of outpatients, emergency patients and inpatients, number of radiotherapy staff, number of electron accelerators ( r=0.311, 0.893, 0.956, P<0.05). Meanwhile, the frequency of aterloading brachytherapy was positively correlated with number of outpatients, emergency patients and inpatients, number of radiotherapy staff, number of aterloading brachytherapy units ( r=0.307, 0.966, 0.988, P<0.05). The frequency of radiotherapy was 0.54 patients per 1 000 population in Fujian in 2016. The delivered dose calibration of accelerators was performed in all hospitals involved in line with the relevant regulations, but the number of quality control equipment for radiotherapy was insufficient, such as the QA beam checker or well-type ionization chamber. Conclusions:In recent years, the rapid development of radiotherapy has been seen in Fujian province. The radiotherapy management should focus on standardenized and improved quality control and regulation in future.
