Julin Bristol Julin Bristol is the codename given to a nuclear weapon test conducted at the Nevada Test Site on 26 November 1991. Conducted as part of Operation Julin, the final series of US nuclear tests, it was the last test explosion of a British nuclear weapon. Both the US and UK, as signatories of the Comprehensive Nuclear-Test-Ban Treaty, ceased nuclear testing after Operation Julin.

Cannikin Cannikin was an underground nuclear weapons test performed on November 6, 1971, on Amchitka island, Alaska, by the United States Atomic Energy Commission. The experiment, part of the Operation Grommet nuclear test series, tested the warhead design for the LIM-49 Spartan anti-ballistic missile. With an explosive yield of almost 5-megatons TNT equivalent, the test was the largest underground explosion ever detonated by the United States.

W41 W41 was the designation of an American nuclear warhead, which was investigated during the late 1950s. Intended for use in the SM-64 Navaho cruise missile, the program was cancelled in 1957. The program was brief, considered at the same time as the TX-29, WX-15-X1 and XW-21 warheads. All were eventually replaced as the proposed Navaho warhead by the W39. The W41 was an adaptation of the B41 thermonuclear bomb which was produced in large numbers and served in stockpile for 15 years.

McDonald Ranch House The McDonald Ranch House, also known as Trinity Site, in the Oscura Mountains of Socorro County, New Mexico, was the location of assembly of the world's first nuclear weapon. The active components of the Trinity test "gadget", a plutonium Fat Man-type bomb similar to that later dropped on Nagasaki, Japan, were assembled there on July 13, 1945. The completed bomb was winched up the test tower the following day and detonated on July 16, 1945 as the Trinity nuclear test.

Operation Ivy Operation Ivy was the eighth series of American nuclear tests, coming after "Tumbler-Snapper" and before "Upshot–Knothole". The two explosions were staged in late 1952 at Eniwetok Atoll in the Pacific Proving Ground in the Marshall Islands.

British contribution to the Manhattan Project Britain contributed to the Manhattan Project by helping initiate the effort to build the first atomic bombs in the United States during World War II, and helped carry it through to completion in August 1945 by supplying crucial expertise. Following the discovery of nuclear fission in uranium, scientists Rudolf Peierls and Otto Frisch at the University of Birmingham calculated, in March 1940, that the critical mass of a metallic sphere of pure uranium-235 was as little as 1 to , and would explode with the power of thousands of tons of dynamite. The Frisch–Peierls memorandum prompted Britain to create an atomic bomb project, known as Tube Alloys. Mark Oliphant, an Australian physicist working in Britain, was instrumental in making the results of the British MAUD Report known in the United States in 1941 by a visit in person. Initially the British project was larger and more advanced, but after the United States entered the war, the American project soon outstripped and dwarfed its British counterpart. The British government then decided to shelve its own nuclear ambitions, and participate in the American project.

Operation Aqueduct The United States's Aqueduct nuclear test series was a group of 10 nuclear tests conducted in 1989-1990. These tests followed the "Operation Cornerstone" series and preceded the "Operation Sculpin" series.

B53 nuclear bomb The Mk/B53 was a high-yield bunker buster thermonuclear weapon developed by the United States during the Cold War. Deployed on Strategic Air Command bombers, the B53, with a yield of 9 megatons, was the most powerful weapon in the U.S. nuclear arsenal after the last B41 nuclear bombs were retired in 1976.

Operation Sandstone Operation Sandstone was a series of nuclear weapon tests in 1948. It was the third series of American tests, following Trinity in 1945 and Crossroads in 1946, and preceding Ranger. Like the Crossroads tests, the Sandstone tests were carried out at the Pacific Proving Grounds, although at Enewetak Atoll rather than Bikini Atoll. They differed from "Crossroads" in that they were conducted by the Atomic Energy Commission, with the armed forces having only a supporting role. The purpose of the Sandstone tests was also different: they were primarily tests of new bomb designs rather than of the effects of nuclear weapons. Three tests were carried out in April and May 1948 by Joint Task Force 7, with a work force of 10,366 personnel, of whom 9,890 were military.

Minor Scale Minor Scale was a test conducted on June 27, 1985, by the United States Defense Nuclear Agency (now part of the Defense Threat Reduction Agency) involving the detonation of several thousand tons of conventional explosives to simulate the explosion of a small nuclear bomb. The purpose of the test was to evaluate the effect of nuclear blasts on various pieces of military hardware, particularly new, blast-hardened launchers for the Midgetman ballistic missile.

Salted bomb A salted bomb is a nuclear weapon designed to function as a radiological weapon, producing enhanced quantities of radioactive fallout, rendering a large area uninhabitable. The term is derived both from the means of their manufacture, which involves the incorporation of additional elements to a standard atomic weapon, and from the expression "to salt the earth", meaning to render an area uninhabitable for generations. The idea originated with Hungarian-American physicist Leo Szilard, in February 1950. His intent was not to propose that such a weapon be built, but to show that nuclear weapon technology would soon reach the point where it could end human life on Earth. No intentionally salted bomb has ever been atmospherically tested, however the UK tested a 1 kiloton bomb incorporating a small amount of cobalt as an experimental radiochemical tracer at their Tadje testing site in Maralinga range, Australia, on September 14, 1957. Furthermore the triple "taiga" nuclear salvo test, as part of the preliminary March 1971 Pechora–Kama Canal project, produced substantial amounts of Co-60, with this fusion generated neutron activation product being responsible for about half of the gamma dose now (2011) at the test site.

Nuclear testing at Bikini Atoll The nuclear testing at Bikini Atoll program was a series of 23 nuclear devices detonated by the United States between 1946 and 1958 at seven test sites on the reef itself, on the sea, in the air and underwater. The test weapons produced a combined fission yield of 42.2 Mt of explosive power.

Fallout: An American Nuclear Tragedy Fallout: An American Nuclear Tragedy is a 1989 book by Philip L. Fradkin which was republished in a second edition in 2004. The book is about the radiation exposure of people and their livestock living downwind from the nuclear weapons testing at the Nevada Test Site in the 1950s. The case of "Irene Allen et al. vs. the United States" is used as a framework for the narrative. The court case "resulted in an award of $2.66 million in damages to eight persons with leukemia, one with thyroid cancer, and another with breast cancer".
