Among various physics Keywords: Neutron shielding, 252Cf, GEANT4, Dose rate, ENDF-VI. In conclusion, the composition of the material used for the inner tube of the ionisation chamber should be taken into account when two or more chambers are built. STEP files do not include material information-, mesh volumes, and export them to GDML files. Materials are chosen from the Geant4 material database based Fast neutron detection is critical to the interdiction of illicit special nuclear material , among other potential applications.

The Physics of Radiotherapy X-Rays and Electrons - Peter

The Geant4 simulated results of mass attenuation coefficients of composite materials have been compared with the experimental and theoretical XCOM data and a good agreement has been observed. GEANT4 is a Monte Carlo code originally implemented for high-energy physics applications and is well known for particle transport at high energies. The capacity of GEANT4 to simulate neutron transport in the thermal energy region is not equally well known.
