Abstract
Results are presented from the study of the off-axis radiation field caused by a relativistic, mono-directional electron beam passing through water. Using the Naval Postgraduate School 100 MeV linear accelerator, off-axis radiation dose was measured with calcium fluoride thermoluminescent dosimeters placed at various path lengths out to two radiation lengths. The off-axis dose was calculated using the electron transport code CYLTRAN of the integrated TIGER series of coupled electron/photon Monte Carlo transport codes. Calculations were performed at Los Alamos National Laboratory. Comparison with the results is made and CYLTRAN is found to be in agreement with experimentally measured values. The extension of results from one medium (water) to another (air) appears to be valid.
