[Creation of a crystalline lens radiation exposure defense cover and the effect of radiation exposure decrease on...

Area of Science:

• Medical Physics
• Radiology
• Radiation Protection

Background:

• Interventional radiology (IVR) poses radiation hazards, particularly to the skin and crystalline lens.
• Neurological interventions require careful consideration of radiation exposure for staff.
• The crystalline lens is highly sensitive to radiation, necessitating protective measures.

Purpose of the Study:

• To identify exposure projections that pose a radiation hazard to the crystalline lens during neurological IVR.
• To examine an efficient method for shielding the crystalline lens during these procedures.
• To evaluate the effectiveness of a protective cover for reducing radiation dose to the lens.

Main Methods:

• Analysis of radiation exposure projections during neurological interventions.
• Identification of the projection with maximum crystalline lens radiation exposure (lateral projection).
• Development and testing of a lead plate cover for the X-ray tube collimator.

Main Results:

• The lateral projection was identified as resulting in maximum crystalline lens radiation exposure.
• Maximum radiation exposure to the lens occurred on the X-ray tube side.
• A shaped lead plate installed on the X-ray tube collimator effectively reduced radiation exposure.

Conclusions:

• A lead plate shield effectively protects the crystalline lens from radiation during lateral projections in neurological IVR.
• This shielding method is efficient and does not create redundant shadows in other projections.
• Implementing this protective measure can significantly decrease radiation risks to the lens for radiological technologists.
