Computerized Anatomical Model Man

Abstract : The Computerized Anatomical Model Man is a detailed representation of the radiation transport properties of the human body. It is to be used for computation of the areal density distribution at specified locations in the body. This information is applicable to dose calculations in natural, weapon, reactor, and other radiation environments. The model has two configurations-- standing and seated. Over 2200 individual geometrical shapes have been used to depict the external conformation, the skeleton, and the principal organs. The exterior dimensions are those of the 50th percentile Air Force man; the skeleton and organs were scaled from life-size models to conform to the exterior. The model includes variations of material density and fractional composition by weight due to the principal chemical elements contained in muscle, bone, bone marrow, and organ tissue. The model is compatible with the North American Rockwell Modified Elemental Volume Dose Program. This has been demonstrated by solution of sample problems employing both configurations of the model with the North American Rockwell Program on the CDC 6600 digital computer at the Air Force Weapons Laboratory.
