Radiation Shielding Software
for Medical Physics
Automate NCRP 147, TG-108, and NCRP 151 shielding calculations with transparent, regulator-ready reports
Edit barrier assumptions, materials, and occupancies before generating recommendations.
Review calculated thicknesses and edit final shielding recommendations before export.
Generate report-ready overlays and air kerma distributions for each evaluated barrier.
Track and manage shielding projects across rooms, sites, and teams.
Compute geometry-dependent shielding quantities directly from the treatment room layout.
Define control points and design goals directly on the facility floorplan.
Used by medical physics groups including:
Platform
A rigorous radiation shielding platform that produces professional-grade designs aligned with regulatory guidance
What you get
From first input to final submission
Regulator-ready shielding report
Formatted for direct submission.
Full physicist report
Step-by-step calculation trace.
Editable shielding models
Adjust geometry and barrier assumptions.
Project-based workflow
Save, revise, and manage designs.
Workflows
Our transparent shielding engine is applied across dedicated clinical workflows, ensuring consistency while accounting for modality-specific requirements
General X-ray and CT
Automated shielding calculations for diagnostic imaging suites following NCRP-147 guidelines. Our platform evaluates lead barrier requirements and produces clear, auditable documentation so licensed professionals can efficiently review and approve designs.
PET + SPECT + CT
PET, SPECT, CT, and nuclear medicine suite shielding analysis following AAPM TG-108 and NCRP-147 guidelines. Our system fully accounts for multiple sources and room geometries to determine required shielding with fully transparent assumptions.
Linear Accelerators
Evaluation of linac vault designs against NCRP-151 recommendations. Our platform verifies whether proposed floorplans, barriers, and workload configurations meet regulatory limits, with all calculations and assumptions documented for peer review by qualified physicists.
About
Mosaic Atomics is a transparent radiation shielding design platform for medical physics teams. We replace manual calculations, spreadsheets, and fragmented reference materials with a unified workflow for calculating, reviewing, and documenting shielding designs. Users can define room geometry, assign shielding assumptions, calculate barrier requirements, edit recommendations, and generate reports ready for regulatory review. Mosaic is used in production by medical physics groups including Olympic Health Physics, One Physics, and Colorado Associates in Medical Physics. Built by Applied Physics PhDs from Stanford, Mosaic is designed to make shielding work more consistent, auditable, and efficient across modern healthcare facilities.
