Purpose

To investigate and quantify the influence of the pulsed nature of clinical irradiation beams on the response of a specific type of active personal dosimeter (active personal dosimeter), and to evaluate its impact on individual occupational dose measurements of interventional radiologists and cardiologists.

Methods

Active personal dosimeter responses were compared against passive dosimeters in a controlled experimental setting.

n = 24 occupational APDs

Results

correction added up to 3.1% more radiation dose to readings, previously undercounted

Occupational APDs (max

3.1%

C-arm dosimeters (max

5.52%

More results

Five dosimeters mounted on C-arms showed that 6.61% of recorded events required correction, with a maximum correction of 5.52 ± 0.02%.

Overall, the impact of pulsed radiation on recorded occupational doses was limited.

Conclusion · 1 of 2

Although the overall influence of pulsed radiation beams on active personal dosimeter-recorded doses was modest, verification of potential count-loss effects remains important to ensure the accuracy of cumulative dose measurements.

Conclusion · 2 of 2

With appropriate correction measures, APDs can be reliably used to support optimization of radiological protection for interventional specialists.
