Abstract:Introduction: Intercomparison exercises for individual monitoring dosimetry ensure and verify the accuracy and quality of radiation monitoring services provided to exposed workers. They also help identify potential deviations in monitoring practices and promoting continuous improvements in radiation safety procedures. Generally, under the ISO 14146 standard, the intercomparison excercises are carried out. In this standard the criteria and procedures are specified for the periodic verification of dosimetry services supplying personal and/or area dosemeters (1). The individual monitoring service in Nicaragua has participated in several intercomparison exercises, organized by the International Atomic Energy Agency IAEA, EURADOS and those recently organized by REPROLAM. The purpose of this work is to share the performance Material and Method: Reports with the results of intercomparison exercises such as *THE IAEA 2013 INTERCOMPARISON EXERCISE FOR WHOLE BODY PHOTON DOSEMETERS IN LATIN AMERICA AND THE CARIBBEAN, conducted from 2013 to 2015 under the project RLA9066 *The intercomparison of EURADOS 2020ph WHOLE BODY FOR PHOTON DOSEMETERS *The results from intercomparison of whole body dosimeters ICReprolam2022 and extremity and eye lens ICREPROLAM EXT&cri Results: The results from the 2013 IAEA intercomparison shown that there was a problem with the performance of the dosimetry system in terms of calibration. Improvement was detected with the results of EURADOS 2020ph, results showed that all the data fell within the trumpet curve indicating in general for some qualities underestimation of the dose, the ISO 14146:2018 standard was applied. For both intercomparison whole body and eye lens results are within the trumpet curve, improvement in terms of system calibration was shown with very good agreement between reported dose and conventional irradiation dose for all operational quantities evaluated. Conclusions: In general terms, participation in intercomparison exercises has been a great opportunity for the external dosimetry monitoring service in Nicaragua, as it has allowed demonstrating the improvement of the technical competence of the service by obtaining satisfactory results.
