The media/news broadcasted it with the "first week of june(2006)" I guess in or on the outskirts of Vegas- at the test site – which will also encompass Mohave County AZ for the"viewing " of afffects to say the least. They said it was a non harmful experiment/test- just wondering if anyone has the info or links 2 sites on it. Thanks

Nuclear testing is experimentation with nuclear weapons. Throughout the twentieth century, most nations which have developed nuclear weapons have staged tests of them. Testing nuclear weapons can yield information about how the weapons work (known as "weapons related" testing), as well as how the weapons behave under various conditions and how structures behave when subjected to nuclear explosions ("known as "weapons effects" testing). Additionally, nuclear testing has often been used as an indicator of scientific and military strength and many tests have been overtly political in their intention, and most nuclear weapons states publicly declared their nuclear status by means of a nuclear test.

Nuclear weapons tests are generally classified as being either "atmospheric" (in or above the atmosphere), "underground". or "underwater". Of these, underground testing contained in deep shafts poses the least health risk in terms of fallout.
The first atomic test was detonated by the United States at the Trinity site on July 16, 1945, with a yield approximately equivalent to 20 kilotons. The first hydrogen bomb, codenamed "Mike", was tested at the Enewetak atoll in the Marshall Islands on November 1, 1952, also by the United States. The largest nuclear weapon ever tested was the "Tsar Bomba" of the Soviet Union at Novaya Zemlya, with an estimated yield of around 50 megatons.
