TIMED:A COMPUTER PROGRAM FOR CALCULATING CUMULATED ACTIVITY OF A RADIONUCLIDE IN THE ORGANS OF THE HUMAN BODY AT A GIVEN TIME, t, AFTER DEPOSITION

摘要

TIMED is a computer program designed to calculate cumulated activity, UYi (t), in the various source organs, Yi, at some time t after deposition. TIMED embodies a system of differential equations which describes activity transfer in the lungs, gastrointestinal tract, and other organs of the body. This system accounts for delay of transfer of activity between compartments of the body and radioactive daughters.nThe computer program contains routines which are written in either IBM System/360 or System/370 FORTRAN or IBM System/360 Assembler language. The code is executable on the IBM System/360 or System/370 machines and requires a minimum of 310 K core storage for execution.
