English: Department of Energy, Mound Laboratories, Electronics Laboratory Building (E Building), One Mound Road, Miamisburg, Ohio.
E Building is significant for its operational role in the polonium processing mission of the Mound Laboratory, polonium having importance in the 1940s for its use in nuclear weapon manufacture and atomic energy. As the building changed form and use throughout the Mound Site's history, it reflects the different phases of activity in its physical structure. During the polonium processing era, the building was involved directly with processing as well as offered operational support to the Mound Laboratory. E Building provided efficient facilities for the repair, design, and assemblage of electronic instruments and contained radiation count laboratories equipped with electronic instrumentation to measure radiation activity levels in samples collected from Mound Laboratory.
