Agreement between rates predicted by the semi-analytical model and G4NRF simulation is found at a level of ∼ 1 % in simple test cases and ∼ 3 % in more realistic scenarios, improving upon the ∼ 20 % level of the initial a semi-analytical model book study and establishing a highly-accurate NRF framework Cited by: 3.

Abstract The radiation transport component of atmospheric modelling codes is typically a major contributor to the overall execution time. This paper introduces a fully equivalent operational model (FEOM) as a high speed replacement for traditional transport modules.

Since radiation transport involves the “flow” of particles, a more commonly used quantity is the particle flux, ϕ, which is the number of particles per unit area per unit time. The latter definition of flux poses a problem though, since radiation intensity can vary with the orientation of radiation with respect to the area on which it impinges.

DHPRE software uses Geant4 simulation toolkit for computing organ doses, effective dose and lifetime atributable cancer risk for humans exposed to external radiation field. It is mainly used for patients undergoing X-ray examinations such as radiography, mammography, dental panoramic and CT but can be used for any kind of radiations.

We also include neutral transport to model radiation from recycling neutral atoms. Abstract: We have developed a general-purpose Monte Carlo simulation code, called penMesh, that combines the accuracy of the radiation transport physics subroutines from PENELOPE and the flexibility of a geometry based on triangle the geometric models implemented in most general-purpose codes-such as PENELOPE's quadric geometry-impose some limitations in the shape Cited by: an outline of the rationale behind the scope and structure of the present book.

We will make brief excursions into other kinds of Monte Carlo methods when they they serve to elucidate some point or when there may be a deeper connection to particle-matter interactions or radiation transport in general.

This paper introduces a simple model for subsurface light transport in translucent materials. The model enables efficient simulation of effects that BRDF models cannot capture, such as color bleeding within materials and diffusion of light across shadow boundaries.

Radiation. Radiative heat transfer is included in the model via the solution of the radiation transport equation (RTE) for a gray gas, and in some limited cases using a wide band model.

The RTE is solved using a technique similar to finite volume methods for convective transport, thus the name given to it is the Finite Volume Method (FVM). Radiation transport Radiative heat transfer is included in the model via the solution of the radiation transport equation for a gray gas, and in some limited cases using a wide band model.

The equation is solved using a technique similar to finite volume methods for convective transport, thus the name given to it is the Finite Volume Method (FVM). Surface–to–surface Radiation Model (1) For example in Fluent®, the surface-to-surface radiation model (S2S) can be used to account for the radiation exchange in an enclosure of gray-diffuse surfaces.

Abstract: Radiation transport modeling methods used in the radiation detection community fall into one of two broad categories: stochastic (Monte Carlo) and deterministic.

There are criteria to check this and, in case there’s still doubt, a comparative computation also helps.
