EVALUATION OF AN ACTIVE PERSONAL DOSIMETRY SYSTEM IN INTERVENTIONAL RADIOLOGY AND NEURORADIOLOGY: PRELIMINARY RESULTS

Area of Science:

• Medical Physics
• Radiological Protection
• Health Sciences

Background:

• Active personal dosimeters (APDs) offer real-time radiation monitoring.
• Minimizing operator radiation exposure is crucial in diagnostic and surgical settings.

Purpose of the Study:

• To evaluate the Raysafe i2 APD system's performance in an angiography room.
• To assess the correlation between radiation dose metrics and operator position.
• To determine the APD system's utility in optimizing radiation safety protocols.

Main Methods:

• Preliminary characterization of the APD system, including angular dependence and Hp(10) response.
• Comparison with thermoluminescence dosimeters (TLDs) for correction factor determination.
• Recording APD data for patients and operators during 52 surgical procedures.

Main Results:

• Established APD system characterization under simulated surgical protocols.
• Quantified the correlation between air kerma measurements (KAP, Kar) and operator dose.
• Demonstrated the relationship between operator position and radiation dose received.

Conclusions:

• The Raysafe i2 APD system provides valuable real-time data for radiation dose assessment.
• APD data can guide operators in optimizing their behavior and the use of protective measures.
• The system shows potential for effectively minimizing radiation exposure in interventional procedures.
