Abstract:
Objective:To understand and analyze the individual dose level of occupational external exposure of industrial workers in China from 2009 to 2013, and to provide basic data and scientific basis for radiation protection and radiation protection management.
Methods:Since January 2009, the individual dose monitoring data of industrial workers were collected through the "National radiological health information platform-individual dose monitoring system". The methods of Kruskal-Wallis test and the Mann-Whitney test were used for statistical analysis of monitoring results for different occupational categories from 2009 to 2013.
Results:From 2009 to 2013, a total of 151, 541 people were monitored for the number of industrial radioactive workers, showing a steady upward trend year by year. The average annual effective doses was 1.179 mSv/a. The average annual effective dose of industrial flaw detection, industrial irradiation, luminescent coatings, radioisotope production, logging, accelerator operation and other applications were 0.808, 1.429, 0.315, 1.074, 0.766, 0.576, and 1.510 mSv/a. There was a statistically significant difference in the average annual effective dose between the seven occupational categories (P<0.05) . The average annual effective doses of other application and industrial irradiation workers in 2013 were significantly higher than other occupational categories (P<0.05) .
Conclusion:The average annual effective dose of industrial radiation workers meet the requirements of national standards. The exposure doses of industrial radiation and other application radiation workers are relatively high. The radiation protection workplace protection measures should be further improved and improved, and radiation protection knowledge training should be strengthened to protect their occupational health.
