GREAT - a Monte Carlo Procedure for Calculating Gamma-radiation Environments Above Terrain

Pages : 46
Book Description
The GREAT Monte Carlo Procedure was written for the IBM 1130 Computer to calculate the energy and angle distribution of the scattered gamma-ray flux at a point detector in an air-ground geometry resulting from a plane-isotropic monoenergetic gamma-ray source parallel to the air-ground interface. The source, which is finite and annular in shape, may be positioned below the smooth ground surface to simulate the effects of a source located on rough ground. The point detector is located on the vertical axis of the annular source. Initial photon parameters, path lengths, interactions and scattering angles are obtained by random sampling of appropriate probability distributions. Each photon is traced as it scatters within the defined geometry and estimates are made of the flux contribution at the detector from each collision.

Monte Carlo Method
Author: GRASS - a Monte Carlo Procedure for Calculating Gamma-ray Attenuation of Simple Structures

Book Description
The GRASS Monte Carlo procedure was written in 1130 FORTRAN to calculate gamma-ray attenuation in simple cylindrical structures. GRASS calculates the structure-scattered gamma-ray flux energy distribution and exposure angle distribution at a point on the centerline of an upright cylindrical barrier exposed to gamma rays from a plane source located on, or near, the ground surface. The energy and angle distribution of the flux incident upon the structure is calculated by a related Monte Carlo procedure and is input in a fixed form which describes 1) "uncollided" gamma rays which reach the barrier before having a collision in the air or ground and 2) "scattered" gamma rays incident on the barrier after having at least one collision in the air or ground. GRASS employs a pseudo source based on probability distributions derived from the incident flux distribution.
