Improvements in the dosimetric models of selected benthic organisms

Creator:

Caffrey, Emily Amanda

Abstract:

The International Commission on Radiological Protection (ICRP) has modeled twelve reference animal and plant (RAP) species using simple geometric shapes in Monte–Carlo (MCNP) based simulations. The focus has now shifted to creating voxel phantoms of each RAP to advance the understanding of radiation interactions in nonhuman biota. The work contained...

Development and Application of Voxelized Dosimetric Models for Biota : Characterization of the Uncertainty in the International Commission on Radiological Protection's Wildlife Dosimetry System

Creator:

Caffrey, Emily Amanda

Abstract:

A system for radiological dosimetry for nonhuman biota developed by International Commission on Radiological Protection (ICRP) relies on calculations that utilize the Monte Carlo simulations of simple, ellipsoidal geometries with internal radioactivity distributed homogeneously throughout. In this manner it is quick and easy to estimate whole-body dose rates to biota....
