History
FASTRAD is a radiation tool dedicated to the analysis and design of radiation sensitive systems. The project was created in 1999 and has constantly been improved since. This software can be applied to any radiation related field. TheRadiation CAD interface
This software is dedicated to engineers who do not necessarily have an extensive experience in CAD applications. This user-friendly interface was developed to construct 3D radiation models using simple functions. The main CAD capabilities of the tool are: * Creation of Box, Sphere, Cylinder, Cone and triangular Prism * Insertion of complex 3D geometries coming fromDose calculation and shielding
Once the 3D radiation model is done, the user can perform a deposited dose estimate using the sector analysis module of the software. This ray-tracing module combines the information coming from the radiation model with the information of the radiation environment using a Dose Depth Curve. This dose depth curve gives the deposited dose in a target material (mainly Silicon for electronic devices) behind an Aluminum spherical shielding thickness. This calculation is performed for each detector placed in the 3D model. Even for complex geometries, the efficient and rapid calculation provides two kinds of information: * the 3D distribution mass around each detector * the estimated deposited dose in an isotropic radiation environmentMonte Carlo algorithm
The dose calculation in the software is particularly efficient with the Monte Carlo module (developed through a partnership with the CNES). This algorithm can be used either in a forward process or a reverse one. In the first case, the software manages the transport ofInterface to Geant4
Geant4 is a particle-matter interaction toolkit maintained by a worldwide collaboration of scientists and software engineers. This C++ library contains a wide range of interaction cross section data and models together with a tracking engine of particles through a 3D geometry. The Geant4 interface implemented in the FASTRAD software provides a tool able to create the 3D geometry, define the particle source, set the physics list and create all the resulting source files in a ready-to-compile Geant4 project. The tool is useful for young engineers who need to be driven into the Geant4 world, and who can use FASTRAD as a tutorial tool, or by experts who do not want to spend time on the creation of C++ files that describe the geometry, material, and basic physics and who can use the Geant4 project created by FASTRAD as a base that can be enhanced by specific features relative to their physical application. The Geant4 interface gives the software a wide range of radiation related fields, as Geant4 is already used for space, medical, nuclear, aeronautical and military applications. Its intuitive and powerful radiation CAD capabilities facilitate the engineering process for any radiation sensitive system analysis.Bunker Tool
Another module is the bunker designer tool that calculates the concrete wall thickness of irradiation rooms by considering the room’s geometry, the type and activity of the source and the acceptable dose rate.Technical specifications
