- Abstract:
- Since the discovery of X-rays, it did not take long time to recognize the adverse effects of ionizing radiation on human tissue. have been recognized. To guarantee adequate radiation protection during fluoroscopic guided interventions, sufficient protection devices and also reliable monitoring applications are mandatory. The main purpose of this thesis is to evaluate the use of the latest real-time personnel dosimetry device (RaySafe i3) forestimation of the eye lens dose of medical staff working in the Cath lab. Furthermore, we sought to evaluate the efficacy of radiation protection glasses with regard to several parameters (design of protection glasses, eye level, viewing direction and the type of scattering bodies) and to compare the results with current scientific evidence. The results of this work confirm the reliability of the RaySafe i3-system for monitoring radiation areas. Concerning the estimation of radiation exposure to the lens of eye, the usage of conversion factors is limited. The protective ability of radiation protection glasses in varying experimental setups and different types of glasses is heterogeneous. A wide range of dose reduction factors from 1.1 to 7.9 was determined.
