Operation Cornerstone
The United States's Cornerstone nuclear test series was a group of 11 nuclear tests conducted in 1988–1989. These tests A bomb test may be a salvo test, defined as two or more explosions "where a period of time between successive individual explosions does not exceed 5 seconds and where the burial points of all explosive devices can be connected by segments of straight lines, each of them connecting two burial points and does not exceed 40 kilometers in length". followed the '' Operation Touchstone'' series and preceded the '' Operation Aqueduct'' series.

Operation Touchstone
The United States's Touchstone nuclear test series was a group of 13 nuclear tests conducted in 1987–1988. These tests A bomb test may be a salvo test, defined as two or more explosions "where a period of time between successive individual explosions does not exceed 5 seconds and where the burial points of all explosive devices can be connected by segments of straight lines, each of them connecting two burial points and does not exceed 40 kilometers in length". followed the '' Operation Musketeer'' series and preceded the '' Operation Cornerstone'' series. The series included ''Touchstone Kearsarge'', a joint US-Soviet test as part of the ''Joint Verification Experiment'' (JVE). The JVE's purpose was to provide yield data to both parties about each other's nuclear test sites so that accurate remote measurements could be taken to verify each other's compliance with the Threshold Test Ban Treaty The Treaty on the Limitation of Underground Nuclear Weapon Tests, also known as ...

Nuclear Fallout
Nuclear fallout is the residual radioactive material propelled into the upper atmosphere following a nuclear blast, so called because it "falls out" of the sky after the explosion and the shock wave has passed. It commonly refers to the radioactive dust and ash created when a nuclear weapon explodes. The amount and spread of fallout is a product of the size of the weapon and the altitude at which it is detonated. Fallout may get entrained with the products of a pyrocumulus cloud and fall as black rain (rain darkened by soot and other particulates, which fell within 30–40 minutes of the atomic bombings of Hiroshima and Nagasaki). This radioactive dust, usually consisting of fission products mixed with bystanding atoms that are neutron-activated by exposure, is a form of radioactive contamination. Types of fallout Fallout comes in two varieties. The first is a small amount of carcinogenic material with a long half-life. The second, depending on the height of detonation, is ...
