:''Not to be confused with the anti-nuclear Plowshares Movement''. Project Plowshare was the overall United States term for the development of techniques to use nuclear explosives for peaceful construction purposes. It was the US portion of what are called Peaceful Nuclear Explosions (PNE). Successful demonstrations of non-combat uses for nuclear explosives include rock blasting, stimulation of tight gas, chemical element manufacture (test shot Anacostia resulted in Curium-250m being discovered), unlocking some of the mysteries of the so-called "r-Process" of stellar nucleosynthesis and probing the composition of the Earth's deep crust, creating reflection seismology Vibroseis data which has helped geologists and follow on mining company prospecting.〔http://symposia.obs.carnegiescience.edu/series/symposium4/ms/becker.ps.gz〕〔http://www.ociw.edu/ociw/symposia/series/symposium4/proceedings.html〕 Negative impacts from Project Plowshare’s 27 nuclear projects generated significant public opposition, which eventually led to the program's termination in 1977.〔 These consequences included Tritiated water (projected to increase by CER Geonuclear Corporation to a level of 2% of the then-maximum level for drinking water) and the deposition of fallout from radioactive material being injected into the atmosphere before underground testing was mandated by treaty. ==Rationale== By exploiting the peaceful uses of the "friendly atom" — in medical applications, earth removal, and later in nuclear power plants — the nuclear industry and government sought to allay public fears about nuclear technology and promote the acceptance of nuclear weapons. At the peak of the Atomic Age, the United States Federal government initiated Project Plowshare, involving "peaceful nuclear explosions". The United States Atomic Energy Commission chairman at the time, Lewis Strauss, announced that the Plowshares project was intended to "highlight the peaceful applications of nuclear explosive devices and thereby create a climate of world opinion that is more favorable to weapons development and tests". 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「Operation Plowshare」の詳細全文を読む スポンサード リンク
