The cross section for bremsstrahlung from highly relativistic particles issuppressed due to interference caused by multiple scattering in dense media,and due to photon interactions with the electrons in all materials. We presenthere a detailed study of bremsstrahlung production of 200 keV to 500 MeVphotons from 8 and 25 GeV electrons traversing a variety of target materials.For most targets, we observe the expected suppressions to a good accuracy. Weobserve that finite thickness effects are important for thin targets.Comment: 52 pages, 13 figures (incorporated in the revtex LaTeX file
