Salted bomb
A salted bomb is a
radioactive fallout than unsalted nuclear arms. This fallout can render a large area uninhabitable.[1] 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.[1]
No intentionally salted bomb has ever been atmospherically tested, and as far as is publicly known, none has ever been built.cobalt-59 to radioactive cobalt-60 by fusion-generated neutron activation and this product is responsible for about half of the gamma dose measured at the test site in 2011.[3][4] The experiment was regarded as a failure and was not repeated.[1]
A salted bomb should not be confused with a "dirty bomb", which is an ordinary explosive bomb containing radioactive material which is spread over the area when the bomb explodes. A salted bomb is capable of megatons of explosive force, which can contaminate a far larger area with far more radioactive material than even the largest practicable dirty bomb.
Design
Salted versions of both
fissionable element, is replaced with a metallic salting element. Salted fission bombs can be made by replacing the neutron reflector between the fissionable core and the explosive layer with a metallic element. The energy yield
from a salted weapon is usually lower than from an ordinary weapon of similar size as a consequence of these changes.
The radioactive isotope used for the fallout material would be a high-intensity gamma ray emitter, with a half-life long enough that it remains lethal for an extended period. It would also have to have a chemistry that causes it to return to earth as fallout, rather than stay in the atmosphere after being vaporized in the explosion. Another consideration is biological: radioactive isotopes of elements normally taken up by plants and animals as nutrition would pose a special threat to organisms that absorbed them, as their radiation would be delivered from within the body of the organism.
Radioactive isotopes that have been suggested for salted bombs include
A
Chicken Little while the AEC dismissed his ideas, but scientists debated whether it was feasible or not.[9] The Bulletin of the Atomic Scientists commissioned a study by James R. Arnold, who concluded that it was.[12] In his 1961 essay, Clark suggested that a 50 megaton cobalt bomb did have the potential to produce sufficient long-lasting radiation to be a doomsday weapon, in theory, but was of the view that, even then, "enough people might find refuge to wait out the radioactivity and emerge to begin again."[7][9]
In popular culture
- In Nevil Shute's novel On the Beach (1957), cobalt bombs are mentioned as the cause of the lethal radioactivity that is approaching Australia. The cobalt bomb was a symbol of man's hubris.[13]
- In San Quentin State Prisonsteals a canister of cobalt-60, thinking it contains drugs. He flees to Los Angeles to pawn it, not knowing it could kill him and possibly contaminate the city.
- In the dark comedy Dead Hand mechanism, by the Soviet Union as a 'doomsday device' nuclear deterrent: if the system detects any nuclear attack, the doomsday device will be automatically unleashed. With unfortunate timing, a deranged American general mutinies and orders an attack on the USSR before the Soviet secret device, already activated, could be unveiled to the world. One American bomber piloted by a hapless and unknowing crew gets through to their target; the Dead Hand mechanism works as designed and initiates a worldwide nuclear holocaust. In the film, the Soviet Ambassador says, "If you take, say, fifty H-bombs in the hundred megaton range and jacket them with Cobalt-Thorium G, when they are exploded they will produce a doomsday shroud. A lethal cloud of radioactivity which will encircle the earth for ninety-three years!"[14]
- In the James Bond film Goldfinger (1964), the title character informs Bond he intends to set off a "particularly dirty" atomic device using "cobalt and iodine"[15] in the U.S. Bullion Depository at Fort Knox as part of Operation Grand Slam, a scheme intended to contaminate the gold at Fort Knox to increase value of the gold he has been stockpiling.
- In Roger Zelazny's 1965 Hugo Award–winning novel This Immortal, Earth has suffered a nuclear war many decades ago and some areas still suffer high radiation levels from cobalt bombs, leading to drastic mutations and ecological changes.
- In the fourth act of the classic Star Trek episode "Obsession" (1967), Ensign Garrovick refers to 10,000 cobalt bombs not equaling the power of less than one ounce of antimatter.
- In Beneath the Planet of the Apes (1970) the main character, upon seeing that an underground mutant community worship a doomsday bomb, comments "They finally built one with a cobalt casing" in reference to a cobalt bomb that could wipe out the world. After astronauts Brent and Taylor are shot by an invading army of apes, Taylor's dying act is to detonate the doomsday bomb, obliterating all life on fortieth century Earth.
- In Tom Clancy's novel The Sum of All Fears (1991) it is noted that Israeli Air Force tactical nuclear bombs can optionally be fitted with cobalt jackets "to poison a landscape to all kinds of life for years to come".[16]
- In the video game Metro Exodus (2019), the player visits the Russian city of Novosibirsk which was hit with at least one cobalt warhead during a worldwide nuclear war in the year 2013, resulting in catastrophic levels of radiation, and is the most irradiated area visited in the three Metro games.
- In the video game Detroit: Become Human (2018), the player has the option of detonating an improvised cobalt bomb during certain endings of the game. The detonation of the bomb results in humans evacuating the now-irradiated city of Detroit and the area 50 miles around, though promising to retake it from the androids in the future. Depending on the player's actions, the city is left empty or the androids claim it for their own.
- In a two-part episode of the TV show The Bionic Woman, "Doomsday Is Tomorrow", a cobalt bomb, dubbed by its creator as "the most diabolical instrument of destruction ever conceived by man," is used as a trigger for a more powerful weapon that can render the world lifeless.
