Project Description: 

FLUKA (FLUktuierende KAskade or Fluctuating Cascade) is a general purpose tool for calculations of particle transport and interactions with matter.

FLUKA can simulate, with high accuracy, the interaction and propagation of about 60 different particles in matter, including photons and electrons from 1 keV to thousands of TeV, neutrinos, muons of any energy, hadrons of energies up to 20 TeV (up to 10 PeV by linking FLUKA with the DPMJET code) and all the corresponding antiparticles, neutrons down to thermal energies and heavy ions. The program can also transport polarised photons (e.g., synchrotron radiation) and optical photons.

FLUKA can handle even very complex geometries, using an improved version of the well-known Combinatorial Geometry (CG) package. The FLUKA CG has been designed to track correctly also charged particles (even in the presence of magnetic or electric fields).  It is also possible to describe a complex geometry in terms of "voxels" (tiny parallelepipeds forming a 3-dimensional grid), method that is especially useful when translating a CT scan of a human body into a dosimetry phantom.

Time evolution and tracking of emitted radiation from unstable residual nuclei can be performed online.

FLUKA is supported by the advanced and user friendly interface Flair (, which features a modern and intuitive design and offers a powerful geometry viewer.

Some projects using this technology: 
  • FLUKA: Simulations for Hadron Therapy
    FLUKA is a particle transport and interaction simulation code, originally developed by CERN and INFN for particle physics, which finds applications in a wide range of other domains including medical.
  • FLUKA: Particle Simulations at Your Fingertips
    In 2016, there were eleven requests for FLUKA licences. Mainly from companies performing shielding studies, but also from some in the field of safety, inspection and auditing that requested the technology, as well as companies working in radio-protection related to dismantling activated industrial...
