“…Further support comes from a study by Kopec et al. ( 18 ) who found ratios of H p (3)/H p (10) between 0.7 and 1.1 among technical staff and nurses at one scintigraphy and two PET-CT departments. They also demonstrated the importance of appropriate placement of the eye dosemeter for achieving correct measurements.…”

The eye lens exposure among 16 technicians in two nuclear medicine departments at university hospitals in Finland was investigated by measuring the operational quantity Hp(3) using EYE-D dosemeters. For all workers, the annual mean Hp(3) was estimated to be 1.1 mSv (max. 3.9 mSv). The relation between Hp(3) to routinely monitored personal dose equivalent Hp(10) was clearly correlated. Considering individual dose measurement periods (2–4 weeks), the Hp(3)/Hp(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 Hp(10) (σ2 = 0.04 vs. 0.43 for Hp(10) > 0.1 mSv vs. < 0.1 mSv, respectively), i.e. higher Hp(10) predicts Hp(3) more reliably. Moreover, annual Hp(10) data from national dose register during 2009–2018 were used to derive the annual Hp(3) applying the Hp(3)/Hp(10) ratio. The data from Finnish nuclear medicine departments imply that routine measurements of Hp(3) among nuclear medicine technicians are not justified.

“…The U.S. Radiologic Technologist cohort study was established under a collaboration among the National Cancer Institute, the University of Minnesota, in performing the procedure (5)(6)(7)(8). However, radiation exposure levels can be reduced by using shielding devices and/or reducing the time spent in close proximity to patients who are undergoing a procedure involving radiation.…”

Purpose To estimate the risk of cataract in a cohort of nuclear medicine (NM) radiologic technologists on the basis of their work histories and radiation protection practices. Materials and Methods In the years 2003-2005 and 2012-2013, 42 545 radiologic technologists from a U.S. prospective study completed questionnaires in which they provided information regarding their work histories and cataract histories. Cox proportional hazards models, stratified according to birth-year cohort (born before 1940 or born in 1940 or later) and adjusted for age, sex, and race, were used to estimate hazard ratios (HRs) for the risk of cataract in radiologic technologists according to NM work history practices according to decade. Results During the follow-up period (mean follow-up, 7½ years), 7137 incident cataracts were reported. A significantly increased risk of cataract (HR, 1.08; 95% confidence interval [CI]: 1.03, 1.14) was observed among workers who performed an NM procedure at least once-as opposed to never. Risks of cataract were increased in the group who had performed a diagnostic (HR, 1.07; 95% CI: 1.01, 1.12) or therapeutic (HR, 1.10; 95% CI: 1.04, 1.17) NM procedure. Risks were higher for those who had first performed diagnostic NM procedures in the 1980s to early 2000s (HR, 1.30; 95% CI: 1.08, 1.58) and those who had performed therapeutic NM procedures in the 1970s (HR, 1.11; 95% CI: 1.01, 1.23) and in the 1980s to early 2000s (HR, 1.14; 95% CI: 1.02, 1.29). With the exception of a significantly increased risk associated with performing therapeutic NM procedures without shielding the radiation source in the 1980s (HR, 1.32; 95% CI: 1.04, 1.67), analyses revealed no association between cataract risk and specific radiation protection technique used. Conclusion An increased risk of cataract was observed among U.S. radiologic technologists who had performed an NM procedure at least once. This association should be examined in future studies incorporating estimated lens doses. RSNA, 2017.

“…Wynika z nich, że blisko 80% rejestrowanych dawek skutecznych mieści się w przedziale do 0,1 mSv/kwartał przy dawce granicznej w ciągu 1 roku wynoszącej 20 mSv [6]. Sporadyczne stosowanie manipulatorów podczas czynności wykonywanych z użyciem izotopów promieniotwórczych sprawia, że ręce radiofarmaceutów mogą otrzymywać znaczne dawki promieniowania [7][8][9][10][11][12][13][14][15][16][17][18][19][20]. Ręce pracownika bezpośrednio manipulujące źródłem promieniowania, a osłonięte jedynie rękawiczkami (których zadaniem jest wyłącznie ochrona przed skażeniami), mogą być narażone na znaczne dawki promieniowania.…”
