Jets emanating from active galactic nuclei are simulated here by a boundary-following code as they propagate through a bimodal external medium consisting of an isothermal galactic halo and a hotter, less dense, uniform intergalactic medium (IGM). The maximum linear sizes of the beams are found as functions of the beam and media parameters, and some of the observed radio source size statistics are produced in a theoretical model which includes an IGM with a constant local density and temperature. Monte Carlo simulations are used to find the median distance for plausible distributions of various input parameters for a number of constant values of IGM density and temperature. 31 refs.
