History
Built by the Dresser-Ideco Company for the U.S. Atomic Energy Commission, it was first erected in 1962 in the atomic bomb test area at Yucca Flat, where it was used for an experiment intended to improve understanding the effects of radiation in the atomic bombing of Hiroshima. A bare (unshielded) nuclear reactor on a hoist car could be moved to different heights on the tower; Japanese-type houses were built near the base of the tower and were bombarded with various intensities of radiation.
After the Nuclear Test Ban Treaty banned open-air nuclear testing, the tower was dismantled and despite its immense size moved from its original location to Jackass Flats in Area 25 of the Nevada Test Site, where it was used for Operation HENRE (High Energy Neutron Reactions Experiment), a series of radiation measurement experiments using a small linear accelerator to provide neutrons.

Famous quotes containing the word history:
“... all big changes in human history have been arrived at slowly and through many compromises.”
—Eleanor Roosevelt (1884–1962)
“To summarize the contentions of this paper then. Firstly, the phrase ‘the meaning of a word’ is a spurious phrase. Secondly and consequently, a re-examination is needed of phrases like the two which I discuss, ‘being a part of the meaning of’ and ‘having the same meaning.’ On these matters, dogmatists require prodding: although history indeed suggests that it may sometimes be better to let sleeping dogmatists lie.”
—J.L. (John Langshaw)
“If usually the “present age” is no very long time, still, at our pleasure, or in the service of some such unity of meaning as the history of civilization, or the study of geology, may suggest, we may conceive the present as extending over many centuries, or over a hundred thousand years.”
—Josiah Royce (1855–1916)
