RayXpert® is a 3D modelization software that calculates the gamma dose rate by Monte Carlo. Compatible with Windows, RayXpert® allows Monte Carlo precision while taking advantage of a user-friendly « push-button » graphical interface.
A series of tools simplifies the scenario management (geometry, sources,…) and the modelization and calculation steps. For example, the simulation parameters are all saved, maximizing the recalculation.
All these features assist the user in his analysis, for a precise, efficient and rapid work in the field of Gamma radiation.
3D Import and Design
The interface quickly enables the user to create realistic 3D models, firstly by combining simple solid shapes (CSG), and secondly by importing 3D models made with standard CAD software (CATIA, SolidWorks, Pro-E, AutoCad,...).
Material and radioactive sources
• Pre-defined list (NIST for material, EAF 2010 for radioactive elements)
• Intrinsic material and source definition (composition of elements and radioactive elements)
The particle tracking in the 3D structure is calculated with the Monte Carlo method. The physical process management for particle-matter interactions was programmed based on the GEANT4 physical process treatment.
RayXpert® deals with photon, electron and positron transport in particular.
Multi-source and multi-detector
Several sources and detectors can be simply and simultaneously defined. A completely automated biasing is proposed to accelerate the complex geometry convergence.
The results are the equivalent dose rate (DED H*(10) of the CIPR74) and the photon flux at the detector level.
A calculation window allows you to monitor the DED value and its error rate for each detector, during the simulation.
Validation of results
Comparisons with MCNPx 2.7.0 allowed us to validate photon transport and secondary particles through different materials (concrete, lead, aluminium, nylon,…) and for several sources (Co, Cs, Eu,…).
These tests also allowed us to validate the dose due to scattered radiation in a 3D scene.
