Support and guides

Getting started

1. 1

   Draw the floor plan

   Draw the facility in your CAD tool, such as QCAD or AutoCAD, and save it as a DXF. You can also trace over an image of an existing plan.

2. 2

   Open it in BarrierSIM

   Open the DXF. BarrierSIM keeps your project in the same file, so you can go back to CAD at any time.

3. 3

   Calibrate to scale

   Use the calibration step to set a known distance, so everything is measured in metres.

4. 4

   Add barriers

   Mark walls, doors and screens as barriers, and choose the material and thickness of each.

5. 5

   Add sources

   Place each radioactive source and set its isotope, activity and name.

6. 6

   Run the simulation

   Press Run to see the dose-rate heat map and isodose contours. Adjust barriers and run again until every area meets its limit.

7. 7

   Export the specification

   Export the barrier specification and dose map for the architect and the regulator.
