Active electronic personal dosemeter in interventional radiology.

Area of Science:

• Medical Physics
• Radiology
• Occupational Health

Background:

• Interventional radiology (IR) procedures, particularly percutaneous revascularisation of pelvic and upper leg arteries, involve significant occupational radiation exposure risks for medical staff.
• Traditional dosimetry methods may not fully capture the dynamic nature of radiation exposure during these complex interventions.

Purpose of the Study:

• To assess occupational exposure levels and patterns to scattered X-ray radiation among medical staff during IR procedures.
• To evaluate the utility of a novel active electronic personal dosemeter (AEPD) for real-time monitoring of radiation doses and dose rates.

Main Methods:

• Utilisation of recently developed active electronic personal dosemeters (AEPDs) placed on the chest, above protective aprons, of operators and assistants.
• Continuous measurement and recording of received radiation doses and dose rates as a function of time during percutaneous interventions.
• Analysis of a typical daily pattern encompassing seven percutaneous interventions.

Main Results:

• AEPDs provided continuous, real-time data on occupational radiation doses and dose rates.
• The study captured a unique pattern of occupational doses and dose rates specific to the IR working environment.
• Detailed analysis of a single day's exposure during multiple complex arterial revascularisation procedures was presented.

Conclusions:

• Active electronic personal dosemeters offer a valuable tool for detailed, real-time monitoring of occupational radiation exposure in interventional radiology.
• Understanding the pattern of dose and dose rate variations is crucial for optimizing radiation protection strategies for medical staff in IR.
• The findings contribute to a better characterisation of the occupational radiation environment in IR settings.
