Ocular radiation protection devices significantly reduce radiation exposure during thoracic interventions. Effectiveness varies with device type and examiner height, with closer proximity potentially increasing dose to the right eye.
Area of Science:
- Medical Physics
- Radiological Protection
- Interventional Radiology
Background:
- Occupational radiation exposure is a significant concern for healthcare professionals in interventional radiology.
- Protecting the eyes, particularly the lens, from scattered radiation is crucial to prevent long-term damage.
Purpose of the Study:
- To evaluate the effectiveness of various ocular radiation protection devices.
- To assess the impact of simulated examiner body height on radiation dose reduction.
- To analyze device performance during simulated thoracic interventions.
Main Methods:
- Utilized an anthropomorphic chest phantom and a head phantom with dosimeters simulating an examiner.
- Simulated examiner heights ranged from 160 to 200 cm.
- Measured radiation doses with and without protection devices (garments, glasses, visors).
Main Results:
- Radiation protection devices reduced average dose by 57.7% to 83.4%.
- Increased examiner height sometimes improved dose reduction for eye lenses with specific glasses and visors.
- The right eye received less protection, especially at shorter distances from the scatter source.
Conclusions:
- All tested ocular protection devices significantly lowered radiation exposure.
- Device efficacy is influenced by examiner height and proximity to the radiation source.
- Particular attention is needed for right eye protection at closer distances.
