Aim: To assess a radiation exposure and a quality of radiation protection as to nuclear medicine staff at our department as a eight-years retrospective study. The therapeutic radionuclides as 131I, 153Sm, 186Re, 32P, 90Y and diagnostic ones as a 99mTc, 201Tl, 67Ga, 111In were used.


Material and method. The effective dose was evaluated in the period of 2000-2007 for nuclear medicine physicians (n = 5), technologists (n = 11) and radiopharmacists (n = 2). A personnel film dosimeter and thermoluminescent ring dosimeter for measurement (1-month periods) of personal dose equivalent Hp(10) and Hp(0,07) were used. Dosimeters were worn obligatory within the frame of nation-wide service of personal dosimetry. The total administered activity all radionuclides during these seven years at our department was 23 721 GBq (99mTc 19 671 GBq, 131I 3 246 GBq, others 804 GBq). The administered activity of 99mTc is similar, but the administered activity of 131I in 2007 increased by 272%, as compared with the year 2000.

Results: The arithmetic average and one standard deviation (SD) of an effective dose (mSv) for nuclear medicine physicians were 1.9 ± 0.5, 1.9 ± 0.6, 1.8 ± 0.8, 1.2 ± 0.8, 1.4 ± 0.8, 1.3 ± 0.6, 0.8 ± 0.4 and 1.2 ± 0.7 and for nuclear medicine technologists were 2.3 ± 1.4, 1.9 ± 0.8, 1.7 ± 1.4, 1.0 ± 1.0, 1.1 ± 1.2, 0.9 ± 0.4, 0.7 ± 0.2 and 1.0 ± 0.5 in 2000, 2001, 2002, 2003, 2004, 2005, 2006 and 2007, respectively. The arithmetic average (SD for n = 2 can't be assessed) of the effective dose (mSv) for radiopharmacists were 9.0, 3.2, 1.8, 0.6, 1.3, 0.6, 0.3 and 0.8, respectively. Although the administered activity of 131I increased the average effective dose per year decreased during eight years.

Conclusion: In all three professional groups of nuclear medicine workers a decreasing radiation exposure was found although the administered activity of 131I increased during years 2000-2007. Our observations suggest successful radiation protection measures at our department.
