Shielding calculation services are developed with a technical methodology and international criteria to define materials and thicknesses for primary and secondary barriers.

• Modeling of workload and occupancy factors.
• Assessment by practice type and adjacent area usage.
• Construction recommendations with full technical traceability.

1. Cariari 2024 case: ECORAY HF-525 Plus unit (150 kVp, 1000 mA).
2. Documented technical assumption: 144 patients per week.
3. Methodological basis: NCRP 147 and shielding conclusions by material.
