| Abstract:: |
| Objective To normalize the individual dose monitoring for nationwide radiological workers and to improve individual dose monitoring ability of radiological health monitoring service institutions. Methods The 2017 annual intercomparison was carried out of nationwide external radiation individual dose monitoring result, with summary and analysis completed. Results A total of 283 monitoring service institutions were involved in the 2017 annual intercomparison. Of them, 249 were qualified, 45 excellent and 34 unqualified. The excellent rate was 15.9% and the pass rate 88.0%. Conclusions Most of individual dose institutions could meet better the requirements by the intercomparison, but some deviated from the references to some degree. It is necessary to strengthen the laboratory operation and standardize data processing and to improve the accuracy end precision of measurement result. |
