A model for calculating shielding requirements in diagnostic X-ray facilities

Area of Science:

• Medical Physics
• Radiological Protection
• Diagnostic Imaging

Background:

• Accurate shielding calculations are crucial for radiation safety in diagnostic X-ray facilities.
• Existing models may lead to exaggerated or insufficient shielding requirements.
• Comprehensive factors influencing radiation levels are often not fully integrated into shielding models.

Purpose of the Study:

• To present a novel, integrated model for calculating shielding requirements in diagnostic X-ray facilities.
• To enhance the accuracy and realism of barrier thickness calculations.
• To avoid unjustified exaggerations in shielding design while maintaining safety standards.

Main Methods:

• Development of a new shielding model by combining and modifying existing concepts.
• Inclusion of multiple radiation sources operating at different potentials.
• Accounting for leakage radiation reduction, secondary radiation use factors, and attenuation by equipment and building materials.

Main Results:

• The proposed model provides a more realistic estimation of shielding requirements.
• Demonstrated potential for reducing shielding material compared to conventional methods.
• Calculations confirmed that safety standards for public and staff radiation protection are maintained.

Conclusions:

• The new model offers a more accurate and practical approach to diagnostic X-ray facility shielding.
• Implementation can lead to optimized shielding design, reducing costs and complexity.
• Ensures effective radiation protection through a comprehensive and realistic calculation methodology.
