Objective To measure the individual dose level of external radiation exposure in the industrial radiographers and sealed source workers in Chongqing.
Methods Thermoluminescence dosimetry was used to record the occupational external radiation individual dose in 500 workers during 2011-2012.
Results In 2011-2012, the 272 industrial radiographers' individual doses ranged from 0.01-4.74 mSv/a, and the average of individual dose was 0.145 mSv/a; the 228 sealed source workers' individual doses ranged from 0.01-1.56 mSv/a, and the average of individual dose was 0.075 mSv/a.
Conclusion The industrial protection in Chongqing city is generally at a high level. The annual individual doses of the workers all meet the requirement of corresponding national standard, but the effective doses of industrial radiographers are higher than those of the sealed source workers.
