Thank you.Los Alamos was approved as the site for the main atomic bomb scientific laboratory on November 25,by Brig. Leslie R. Groves and physicist J. Robert Oppenheimer and was given the code name Project Y.

One bomb, using plutonium, was successfully tested on July 16,at a site km miles south of AlbuquerqueNew Mexico. The first atomic bomb to be used in warfare used uranium. The explosion, which had the force of more than 15, tons of TNT, instantly and completely devastated Of this number some 70, were killed immediately, and by the end of the year the death toll had surpassedThe next atomic bomb to be exploded was of the plutonium type; it was dropped on Nagasaki on August 9,producing a blast equal to 21, tons of TNT.

The Japanese initiated surrender negotiations the next day. The great temperatures and pressures created by fission explosion are also used to initiate fusion and thus detonate a thermonuclear bomb.

Scientists hoped that exploding the bomb at an elevated height would reduce the amount of radioactive dust raised by the explosion. They also needed to simulate the air-drop method of deployment that was eventually used by the real bombs. Fat Man was detonated over Nagasaki, Japan less than a month after the Trinity test.

Exploding with an energy equal to about 20 kilotons of TNT, the blast carved a crater in the Earth more than 1, feet wide and 10 feet deep. Radioactive fallout from the blast was detected as far away as Indiana. Because of its importance in the warthe Trinity test was conducted in secret. Little was known about the dangers of radiation exposure in the s, so local residents were not warned or evacuated in advance of—or even following—the test. As a result, people in surrounding areas were exposed to radiation by breathing contaminated air, eating contaminated foods, and drinking affected water and milk.

Some ranches were located within 15 miles of ground zero, and commercial crops were grown nearby. In the hours after the blast, five monitoring teams traveled along local roads recording radiation levels. The highest radiation levels from Trinity were measured in a swath 12 miles long and one mile wide that started near an area 16 miles northeast of ground zero. Around nearby ranches, exposure rates around 15 Roentgen per hour were measured just three hours after detonation.

Currently, the Nuclear Regulatory Commission states that members of the public should not receive more than 2 millirem about 0. The exposure rates following the Trinity test were more than 10, times this recommended dose level.

Widner, the director of the new CDC study, said he thinks evacuations would have certainly been arranged if scientists and physicians had known about the long-term effects of radiation exposure, even if the publicity threatened the mission. Trinity is now open twice a year to the public, on the first Saturdays of April and October for six hours each time.

According to the public affairs office at White Sands, a one-hour visit to ground zero will result in a whole body exposure of one-half to one millirem.

Plans for the creation of a uranium bomb by the Allies were established as early aswhen Italian emigre physicist Enrico Fermi met with U. Navy department officials at Columbia University to discuss the use of fissionable materials for military purposes.

That same year, Albert Einstein signed a letter to President Franklin Roosevelt supporting the theory that an uncontrolled nuclear chain reaction had great potential as a basis for a weapon of mass destruction.

But in earlywith the United States now at war with the Axis powers, and fear mounting that Germany was working on its own uranium bomb, the War Department took a more active interest, and limits on resources for the project were removed. Brigadier-General Leslie R. Groves, himself an engineer, was now in complete charge of a project to assemble the greatest minds in science and discover how to harness the power of the atom as a means of bringing the war to a decisive end. The Manhattan Project so-called because of where the research began would wind its way through many locations during the early period of theoretical exploration, most importantly, the University of Chicago, where Enrico Fermi successfully set off the first fission chain reaction.

Here theory and practice came together, as the problems of achieving critical mass—a nuclear explosion—and the construction of a deliverable bomb were worked out. Finally, on the morning of July 16, in the New Mexico desert miles south of Santa Fe, the first atomic bomb was detonated.

The scientists and a few dignitaries had removed themselves 10, yards away to observe as the first mushroom cloud of searing light stretched 40, feet into the air and generated the destructive power of 15, to 20, tons of TNT.

The tower on which the bomb sat when detonated was vaporized. The question now became—on whom was the bomb to be dropped? Germany was the original target, but the Germans had already surrendered. The only belligerent remaining was Japan. But if you see something that doesn't look right, click here to contact us! On July 16,Amazon officially opens for business as an online bookseller.
