BACKGROUND/PURPOSE: The development of dental radiology in Taiwan has been over a century. This study explored mainly the profile of dental radiation workers and their occupational radiation exposure in Taiwan from 2013 to 2020.
This study used the secondary data analysis to survey mainly the changes of manpower of the dental radiation workers and their occupational radiation exposure in Taiwan from 2013 to 2020.
The number of monitored dental radiation workers increased from 678 in 2013 to 770 in 2020. However, the proportion of monitored dental radiation workers to the total monitored medical radiation workers decreased from 4.29% in 2013 to 3.67% in 2020. Although the number of monitored dental radiation workers increased, the number of the measurably exposed dental radiation workers decreased from 2013 to 2020. The annual collective exposure dose fluctuated from 5.21 man-Sv to 15.47 man-Sv, but it showed a decreasing trend. Furthermore, the mean annual effective exposure dose of total monitored dental radiation workers (0.01-0.02 mSv) and that of the measurably exposed dental radiation workers (0.15-1.11 mSv) were relatively low among various medical radiation workers. In overall, the proportion of medical radiation technologists to dentists varied from 0.41 to 0.45.
Although the number of monitored dental radiation workers increase, the number of the measurably exposed dental radiation workers, the proportion of the measurably exposed dental radiation workers to the total monitored dental radiation workers, and the annual collective exposure dose for monitored dental radiation workers decrease from 2013 to 2020.
背景/目的：台湾牙科放射学的发展已有一个多世纪。本研究主要探讨了2013年至2020年台湾牙科放射工作人员的概况及其职业辐射暴露情况。
本研究采用二次数据分析，主要调查2013年至2020年台湾牙科放射工作人员的人力变化及其职业辐射暴露情况。
受监测的牙科放射工作人员数量从2013年的678人增加到2020年的770人。然而，受监测的牙科放射工作人员占受监测医疗放射工作人员总数的比例从2013年的4.29%降至2020年的3.67%。尽管受监测的牙科放射工作人员数量有所增加，但从2013年到2020年，可测量到辐射暴露的牙科放射工作人员数量却减少了。年集体暴露剂量在5.21人-希沃特至15.47人-希沃特之间波动，但呈下降趋势。此外，在各类医疗放射工作人员中，受监测的牙科放射工作人员的年平均有效暴露剂量（0.01 - 0.02毫希沃特）和可测量到辐射暴露的牙科放射工作人员的年平均有效暴露剂量（0.15 - 1.11毫希沃特）相对较低。总体而言，医疗放射技师与牙医的比例在0.41至0.45之间。
尽管受监测的牙科放射工作人员数量增加，但从2013年到2020年，可测量到辐射暴露的牙科放射工作人员数量、可测量到辐射暴露的牙科放射工作人员占受监测牙科放射工作人员总数的比例以及受监测牙科放射工作人员的年集体暴露剂量均有所下降。
