Operation Teapot was a series of fourteen nuclear test explosions conducted at the Nevada Test Site in the first half of 1955.
During shot "Wasp", ground forces took part in Exercise Desert Rock VI which included an armored task force "Razor" moving to within 900 meters of ground zero, under the still-forming mushroom cloud.

Tsar Bomba is the nickname for the AN602 hydrogen bomb, the largest and most powerful nuclear weapon ever detonated throughout history.
Developed by the Soviet Union, the bomb was originally designed to have a yield of about 100 megatons of TNT (420 PJ); however, the bomb yield was reduced to 50 megatons - one quarter of the estimated yield of the 1883 eruption of Krakatoa - in order to reduce nuclear fallout.

The first nuclear artillery test was on May 25, 1953 at the Nevada Test Site. Fired as part of Operation Upshot-Knothole and codenamed Shot GRABLE, a 280 mm shell with a gun-type fission warhead was fired 10,000 m and detonated 160 m above the ground with an estimated yield of 15 kilotons. This was the only nuclear artillery shell ever actually fired in the US test program.

Tracking and locating hazardous radioactive materials has become an immense concern for the United States Department of Homeland Security. In the wrong hands, materials snatched from a hospital or a nuclear plant could be used to build a "dirty bomb" that might cause major harm to human health and the environment.
Researchers at the University of New Hampshire (UNH) have now built a highly sensitive device for detecting radioactive materials remotely, using spare detectors from NASA's Compton Gamma-Ray Observatory. The detectors were originally intended to measure gamma rays in space.

A Short History of Nuclear Weapons
The first decades of the twentieth century were a period of stunning advances in physics and chemistry. It seemed that every experiment, technical paper, and scientific conference revealed some new aspect of nature. Ordinary materials were shown to be constructed of complex combinations of ninety-two different types of atoms, which, with diameters of a few billionths of an inch, were considered the fundamental building blocks of nature. Later experiments showed that atoms were themselves constructed of a tiny central nucleus - with a diameter a few millionths of that of an atom - surrounded by a cloud of electrons, somewhat analogous to miniature solar systems.

The crash of a B-52 aircraft, armed with nuclear warheads, in north-west Greenland back in 1968 has left a lasting legacy, according to those involved in the clear up and those who live in the region now.
There are claims of long-term damage to the environment and to the heath of individuals, allegations disputed by the governments involved.

Last year's flooding put the atomic weapons' establishment at Burghfield near Reading out of action for nearly nine months and 'came close to overwhelming' buildings where nuclear warheads are assembled.
Documents released under the Freedom of Information Act to the Nuclear Information Service and seen by Channel 4 News, show that managers at AWE knew about flood risks but neglected to protect key facilities.

A Czech webcam which was streaming pastoral pictures of a local beauty spot, was hacked into, and an image of a nuclear mushroom cloud was inserted into the background. Unfortunately, the video was also then broadcast live on Czech television.
The incident occurred in June 2007, on the Panorama TV programme.

Two things have happened this week to make it a special one for the veterans of British nuclear bomb testing in the Pacific.
 Firstly, it is the fifty year anniversary of the event.
 Secondly, a study has been released showing that many of them suspected all along they have serious genetic damage
