Stylized Computational Phantoms Developed at ORNL and Elsewhere

ByKeith F. Eckerman, John W. Poston, Sr., Wesley E. Bolch, and X. George Xu

In internal radiation dosimetry, a phantom is a mathematical representation of the human body which, when coupled with a Monte Carlo radiation transport computer code, can be used to estimate the absorbed dose to tissue and organs of the body from radionuclides distributed in the body-either uniformly or located in speci c organs. The phantom description includes information on the elemental compositions and densities of the body or speci c organs to allow the Monte Carlo code to track the radiation interactions and energy deposition in the body.
