    Area of Science:

    • Medical Physics
    • Radiological Sciences
    • Interventional Radiology

    Background:

    • Minimizing occupational radiation exposure is crucial in interventional radiology.
    • Scatter radiation poses a significant risk to healthcare personnel during procedures.
    • Existing shielding solutions can sometimes impede patient access.

    Purpose of the Study:

    • To introduce and evaluate a novel, simple shielding device for reducing scatter radiation exposure.
    • To assess the efficacy of the device in interventional procedures like percutaneous renal stone removal.
    • To demonstrate that the shield does not compromise patient access.

    Main Methods:

    • A device with 0.75-mm lead equivalent shielding was designed.
    • The shield was applied to the side of a patient during simulated procedures (phantom studies).

  • Scatter exposure levels were measured to quantify the reduction in radiation dose.

    • Main Results:

    • The device achieved a reduction in personnel scatter radiation exposure by up to 75%.
    • Phantom studies confirmed the effectiveness of the shielding.
    • The design allows for unimpeded access to the patient during procedures.

    Conclusions:

    • This simple shielding device offers a highly effective method for reducing occupational radiation exposure.
    • The non-obstructive nature of the shield enhances its practicality in clinical settings.
    • Surface shielding is a viable strategy for radiation protection in interventional radiology.
