Radiation dose distribution measurements have been carried out by the Naval Surface Warfare Center (NSWC) using 200 and 391 MeV electron beams completely penetrating layers of Aluminum, Lead and Aluminum, Polymethyl Melthacrylate (PMMA), and PMMA sandwiching an air gap. For the case of 391 MeV electrons, the results have been compared previously to the corresponding distributions predicted by the Monte Carlo simulation codes EGS3 and ACCEPT (Ref. 1). Those measurements/predictions for 391 MeV are here compared to predictions by the CYLTRAN electron/photon transport code, and the 200 MeV measurements done by NSWC are compared to CYLTRAN calculations. The CYLTRAN code predictions agree well with measurements at 391 MeV. Comparison of CYLTRAN calculations with the NSWC results for 200 MeV indicates possible saturation of the detectors used to take the measurements. The distribution of energy dose within the target has a large dependence on the location of the air gap. The variation in dose distribution is caused by the change in target geometry resulting from insertion of the air gap.
