Atomic Test Effects in the Nevada Test Site Region
Thirty-one atomic fission weapons, weapon prototypes, or experimental devices were fired in Nevada from January 1951 to January 1955. All were relatively small in explosive power. They ranged from less than one kiloton up to considerably less than 100 kilotons. (A kiloton is equal to 1,000 tons of TNT.) The forces released by test detonations in Nevada are very small compared to the tremendous forces released by the large fission and hydrogen weapons tested in the Pacific. So-called "H-bombs" are not tested in Nevada. Despite their relatively low yield, Nevada tests have clearly demonstrated their value to all national atomic weapons programs. Each Nevada test has successfully added to scientific knowledge needed for development and for use of atomic weapons, and needed to strengthen our defense against enemy weapons. An unusual safety record has been set. There were instances of property damage from blast, such as broken windows. Exposure to Flash Past Experience With Flash The U.
