Features

From floor plan to shielding specification

Everything a physicist needs to lay out, simulate and document facility shielding.

  • Your own DXF floor plans

    Draw the facility in AutoCAD or QCAD and open the DXF. It stays your project file.
  • Calibrated to scale

    Calibrate the drawing to metric units, then lay out walls and sources with grid, angle and endpoint snapping.
  • Barriers and sources

    Mark lines as concrete, lead or other barriers, and points as sources with isotope and activity.
  • Dose-rate heat maps

    Every source is ray-traced to every grid cell, through every barrier it crosses.
  • Isodose contours

    Vector isodose lines at logarithmic levels, adjustable without re-running the simulation.
  • A traceable specification

    Export the barrier specification with its method, assumptions and data sources, ready for architects and regulators.
