As even low doses may contribute to stochastic health effects, enhanced radiological protection measures are warranted. This study aimed to systematically quantify the radiation exposure of radiologic technologists under routine clinical conditions and in an experimental setting.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Radiation dose exposure was monitored over one month using three official dosimeters placed at defined locations within the angiography suite, using the floor-mounted C-arm as a reference point. Dose values were extrapolated to estimate annual exposure. Additionally, experimental dose rate measurements were performed at eight locations and three height levels (foot, torso, eye) under standardized conditions using both standard and low-dose DSA protocols.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Official dosimeter readings averaged less than 2% of the reference value at the C-arm. The extrapolated annual occupational radiation exposure was low (0.44 mSv), with the highest value of 1.03 mSv near the door to the supply room. Experimental measurements revealed average radiation dose rates of 885 \u00b5Sv\/h; with a wide range from: 12 to 6109 \u00b5Sv\/h. Dose rates were more strongly influenced by the shielding effect of stationary protective equipment (reduction factor of 31) than by spatial distance. The highest radiation exposure occurred at foot level. Low-dose protocols reduced ambient radiation by an average of 23%.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Occupational exposure remained well below legal thresholds but varied spatially.
