title: Projected whole-body career doses for radiation workers in Canada.
abstract: Projected whole-body career doses have been calculated from Canadian exposure data contained in the National Dose Registry, using the straight extrapolation of accumulated annual doses to a 40-y period, as described in the 1977 UNSCEAR report (UNSCEAR77). The calculations are broken down by type of employment. The results are compatible with earlier publications. Double regressions provided trends of projected career doses with increasing length of employment and with progressing date of enrollment into the registry. The career doses fit a log-normal or a hybrid log-normal distribution for occupations with low and high exposures, respectively.
