Abstract: The eye lens exposure among 16 technicians in two nuclear medicine departments at university hospitals in Finland was investigated by measuring the operational quantity H-p(3) using EYE-D dosemeters. For all workers, the annual mean H-p(3) was estimated to be 1.1 mSv (max. 3.9 mSv). The relation between H-p(3) to routinely monitored personal dose equivalent H-p(10) was clearly correlated. Considering individual dose measurement periods (2-4 weeks), the H-p(3)/H-p(10) ratio was 0.7 (Pearson's coefficient r = 0.90, p <0.001, variation of ratio 0.1-2.3). The variation decreased considerably with increasing H-p(10) (sigma(2) = 0.04 vs. 0.43 for H-p(10) > 0.1 mSv vs. <0.1 mSv, respectively), i.e. higher Hp(10) predicts H-p(3) more reliably. Moreover, annual H-p(10) data from national dose register during 2009-2018 were used to derive the annual H-p(3) applying the H-p(3)/H-p(10) ratio. The data from Finnish nuclear medicine departments imply that routine measurements of H-p(3) among nuclear medicine technicians are not justified.
