    A retrospective dosimetry based on work history information has been used for an epidemiological study of Japanese radiological technologists although much uncertainty is involved.

    Work history and self-reported doses have been investigated for individual dosimetry of 1219 radiological technologists and researchers using questionnaires.

    The reconstructed doses by retrospective dosimetry have been compared with self-reported doses in order to examine the validity of the estimates by dose reconstruction.

    There was no good correlation between the reconstructed doses and self-reported doses.

    The ratios of the former to the latter for each subject distributed 3.4 x 10-3 to 7.4 X 103 with a median value of 4.5. These results suggest the possibility of overestimation of radiation dose by dose reconstruction.

    The dose reconstruction is necessary, however, especially in the periods before the introduction of individual dose monitoring.
