Abstract
[ Objective ] To analyze personal dose of occupational external for radiation in radiological professionals in Ningbo, and to provide basis for the assessment of radiation protection and physical dose of radiological accidents in workplace. [ Methods ] Thermoluminescence dosimetry was used to detect the personal radiation dose of radiological professionals in selected medical institutions and factories in Ningbo. [ Results ] Of the 1563 participants investigated, the average annual individual dose equivalent was 0.2980mSv in 2011, among whom 1528 participants were at individual averages lower than 2mSv, 28 were between 2mSv and 5mSv, 5 were between 5 mSv and 20mSv, and 2 exceeded 20mSv. The highest average annual dose equivalent were found in medical staff from township and private clinics, followed by professionals that engaged in county level hospitals, factories, and municipal hospitals. The radiotherapists received the highest personal dose of external radiation, while the technicians responsible for accelerators did the lowest. [ Conclusion ] The occupational external radiation exposure is generally at a low level for radiological professionals in Ningbo and the radition protection work goes well.关键词
