It is well known that beamstrahlung and bremsstrahlung take place over a finite formation zone distance. If something disturbs the electron during this time, the emission can be suppressed. In this paper, we examine the Landau-Pomeranchuk-Migdal (LPM) effect and other LPM-like effects, such as the longitudinal density (di- electric) suppression and EM field suppression of beamstrahlungand bremsstrahlungin e[sup +]e[sup -] linear colliders. We show that while the LPM effect and the density effect are not sufficient in suppressing these radiations, the strong EM field of the opposing beam does help to suppress bremsstrahlung.
