A computer program has been developed at Texas A M University to model the transport and energy deposition of electrons and photons for use in internal dose estimation. The code incorporates photon and electron transport subroutines with the geometry subroutine from ALGAM. A user code, called INDOSE, was used to provide estimates of the absorbed fraction of energy for selected target organs of a mathematically described human phantom. The INDOSE code is comprised of three primary sections: the MAIN program, AUSGAB, the scoring routine, and POSITIN, the geometry tracking routine. The geometry routine contains a mathematical representation of Reference Man. The total-body phantom consists of three principal sections and of three types of tissue: lung, skeletal tissue, and soft tissue. The skeletal system represents the total content of the intact skeleton and includes both bone and marrow. This material is considered to be distributed homogeneously throughout the phantom. In 1988, a research proposal was submitted to the Department of Energy (DOE) to continue the code development for use in internal dosimetry calculations, particularly those related to diagnostic nuclear medicine procedures. This document presents a progress report for the completion of tasks accomplished over the period of July 1989 through January 1990. 39 refs., 45 figs., 24 tabs.
