It is the largest aerobiology chamber ever constructed and was placed on the National Register of Historic Places in 1977. ==The structure== The stainless steel test sphere, a cloud chamber used to study static microbial aerosols, is a four-story high, 131-ton structure. Its , carbon steel hull was designed to withstand the internal detonation of "hot" biological bombs without risk to outsiders. It was originally contained within a cubical brick building. Its purpose was the study of infectious agent aerosols and testing of pathogen-filled munitions. The device was designed to allow exposure of animals and humans to carefully controlled numbers of organisms by an aerosol (inhalational) route. Live, tethered animals were inserted into the chamber along with BW bombs for exposure tests. Human volunteers breathed metered aerosols of Q fever or tularemia organisms through ports along the perimeter of the sphere. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「One-Million-Liter Test Sphere」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
