Atomic Age

In 1901, Frederick Soddy and Ernest Rutherford discovered that radioactivity was part of the process by which atoms changed from one kind to another, involving the release of energy. Soddy wrote in popular magazines that radioactivity was a potentially "inexhaustible" source of energy and offered a vision of an atomic future where it would be possible to "transform a desert continent, thaw the frozen poles, and make the whole earth one smiling Garden of Eden." The promise of an "atomic age," with nuclear energy as the global, utopian technology for satisfying human needs has been a recurring theme ever since. But, "Soddy also saw that atomic energy could possibly be used to create terrible new weapons". The concept of a nuclear chain reaction was hypothesized in 1933, shortly after James Chadwick's discovery of the neutron. Only a few years later, in December 1938, Otto Hahn and his assistant, Fritz Strassmann, discovered nuclear fission. Hahn understood that a "burst" of the atomic nuclei had occurred. Lise Meitner and Otto Frisch gave a full theoretical interpretation and named the process "nuclear fission" in their paper published published in the Nature journal on Feb 11, 1939. The first artificial self-sustaining nuclear chain reaction took place at Chicago Pile-1, in December 1942, under the leadership of Enrico Fermi. == World War II ==

The phrase Atomic Age was coined by William L. Laurence, a journalist with The New York Times, who became the official journalist for the Manhattan Project, which developed the first nuclear weapons. He witnessed both the Trinity test and the bombing of Nagasaki and went on to write a series of articles extolling the virtues of the new weapon. His reporting before and after the bombings helped to brighten public awareness nuclear technology's potential and in part motivated development of the technology in the U.S. and in the Soviet Union. The Soviet Union would go on to test its first nuclear weapon in 1949. Also in 1949, U.S. Atomic Energy Commission chairman, David Lilienthal stated that, "atomic energy is not simply a search for new energy, but more significantly a beginning of human history in which faith in knowledge can vitalize man's whole life". == 1950s ==

in the background. Scenes such as this were typical during the 1950s. From 1951 to 1962 the government conducted 100 atmospheric tests at the nearby Nevada Test Site. The phrase gained popularity as a feeling of nuclear optimism emerged in the 1950s in which it was believed that all power generators in the future would be atomic. The atomic bomb would render all conventional explosives obsolete, and nuclear power plants would do the same for power sources such as coal and oil. There was a general feeling that everything would use a nuclear power source of some sort, in a positive and productive way, from irradiating food to preserve it, to the development of nuclear medicine. Ahead was an age of peace and plenty, in which atomic energy would "provide the power needed to desalinate water for the thirsty, irrigate the deserts for the hungry, and fuel interstellar travel deep into outer space". This use would render the Atomic Age as significant a step in technological progress as the first smelting of bronze, of iron, or the commencement of the Industrial Revolution. The Atomic Age included even cars, leading Ford Motor Company to display to the public the Ford Nucleon concept car in 1958. People believed in the promise of golf balls that could always be found, and nuclear-powered aircraft, which the U.S. federal government even spent US$1.5 billion researching. The very idea of splitting the atom had an almost magical grip on the imaginations of inventors and policymakers. As soon as someone said—in an even mildly credible way—that these things could be done, then people quickly convinced themselves ... that they would be done. Some media reports predicted that thanks to the giant nuclear power stations of the near future, electricity would soon become much cheaper and that electricity meters would be removed, because power would be "too cheap to meter." When the Shippingport reactor went online in 1957 it produced electricity at a cost roughly ten times that of coal-fired generation. Scientists at the AEC's own Brookhaven Laboratory "wrote a 1958 report describing accident scenarios in which 3,000 people would die immediately, with another 40,000 injured". But Shippingport was an experimental reactor using highly enriched uranium (unlike most power reactors) and originally intended for a (cancelled) nuclear-powered aircraft carrier. Kenneth Nichols, a consultant for the Connecticut Yankee and Yankee Rowe nuclear power stations, wrote that while considered "experimental" and not expected to be competitive with coal and oil, they "became competitive because of inflation ... and the large increase in price of coal and oil." He wrote that for nuclear power stations the capital cost is the major cost factor over the life of the plant, hence "antinukes" try to increase costs and building time with changing regulations and lengthy hearings, so that "it takes almost twice as long to build a (U.S.-designed boiling-water or pressurized water) atomic power plant in the United States as in France, Japan, Taiwan or South Korea." French pressurized-water nuclear plants produce 60% of their electric power and have proven to be much cheaper than oil or coal. Atomic City During the 1950s, Las Vegas earned the nickname "Atomic City" for becoming a hotspot where tourists would gather to watch above-ground nuclear weapons tests taking place at the Nevada Test Site. Following the detonation of Able--one of the first atomic bombs dropped at the Nevada Test Site--the Las Vegas Chamber of Commerce began advertising the tests to tourists as an entertainment spectacle. The detonations proved popular, and casinos throughout the city capitalized on the tests by advertising hotel rooms or rooftops that offered views of the testing site, or by planning "Dawn Bomb Parties" where people would come together to celebrate the detonations. Most parties started at midnight, and musicians would perform at the venues until 4:00 a.m., when the party would briefly stop so that guests could silently watch the detonation. Some casinos further capitalized on the tests by creating so called "atomic cocktails"--a mixture of vodka, cognac, sherry and champagne. Meanwhile, groups of tourists would drive out into the desert with family or friends to watch the detonations. Despite the health risks associated with nuclear fallout, tourists and viewers were told to simply "shower". Later on, however, anyone who had worked at the testing site or lived in areas exposed to nuclear fallout fell ill and developed cancer and suffered pre-mature deaths at higher rates. == 1960s ==

The term "atomic age" was initially used in a positive, futuristic sense, but by the 1960s the threats posed by nuclear weapons had begun to edge out nuclear power as the dominant motif of the atom. In the Thunderbirds TV series, a set of vehicles was presented that were imagined to be completely nuclear, as shown in cutaways presented in their comic-books. Project Plowshare By exploiting the peaceful uses of the "friendly atom" in medical applications, earth removal and subsequently in nuclear power plants, the nuclear industry and U.S. government sought to allay public fears about nuclear technology and promote the acceptance of nuclear weapons. At the peak of the Atomic Age, the U.S. initiated Project Plowshare, involving "peaceful nuclear explosions". The United States Atomic Energy Commission (AEC) chairman announced that Plowshare was intended to "highlight the peaceful applications of nuclear explosive devices and thereby create a climate of world opinion that is more favorable to weapons development and tests". Plowshare "was named directly from the Bible itself, specifically Micah 4:3, which states that God will beat swords into ploughshares, and spears into pruning hooks, so that no country could lift up weapons against another". == 1970s to 1990s ==

. The Chernobyl Nuclear Power Plant can be seen on the horizon. French advocates of nuclear power developed an aesthetic vision of nuclear technology as art to bolster support for the technology. Leclerq compares the nuclear cooling tower to some of the grandest architectural monuments of Western culture: In 1973, the AEC predicted that by the turn of the 21st century, 1,000 reactors would be producing electricity for homes and businesses across the U.S. But after 1973, reactor orders declined sharply as electricity demand fell and construction costs rose. Many orders and partially completed plants were cancelled. By the late 1970s, nuclear power suffered a remarkable international destabilization, as it was faced with economic difficulties and widespread public opposition, coming to a head with the Three Mile Island accident in 1979 and the Chernobyl disaster in 1986, both of which adversely affected the nuclear power industry for decades thereafter. A cover story in the 11 February 1985 issue of Forbes magazine addresses the overall management of the nuclear power program in the United States: The failure of the U.S. nuclear power program ranks as the largest managerial disaster in business history, a disaster on a monumental scale ... only the blind, or the biased, can now think that the money has been well spent. It is a defeat for the U.S. consumer and for the competitiveness of U.S. industry, for the utilities that undertook the program and for the private enterprise system that made it possible. In a little over 30 years, the development of a civilian nuclear power program saw a rapid decline. == 21st century ==

in Japan, the worst nuclear accident in 25 years, displaced 50,000 households after radiation leaked into the air, soil and sea. In the 21st century, the label of the "Atomic Age" connotes either a sense of nostalgia or naïveté and is considered by many to have ended with the fall of the Soviet Union in 1991, though the term continues to be used by many historians to describe the era following the conclusion of the Second World War. Atomic energy and weapons continue to have a strong effect on world politics in the 21st century. The nuclear power industry has improved the safety and performance of reactors and has proposed new, safer (but generally untested) reactor designs, but the industry cannot guarantee that the reactors will be designed, built, and operated correctly. According to UBS AG, the Fukushima accident cast doubt on whether even an advanced economy like Japan can master nuclear safety. Catastrophic scenarios involving terrorist attacks are also conceivable. An interdisciplinary team from MIT has estimated that if nuclear power use tripled from 2005 to 2055 (2%–7%), at least four serious nuclear accidents would be expected in that period. In September 2012, in reaction to the Fukushima disaster, Japan announced that it would completely phase out nuclear power by 2030, although the likelihood of this goal became unlikely during the subsequent Abe administration. Germany planned to completely phase out nuclear energy by 2022 but was still using 11.9% in 2021. In 2022, following the Russian invasion of Ukraine, the United Kingdom pledged to build up to 8 new reactors to reduce their reliance on gas and oil and hopes that 25% of all energy produced will be by nuclear means. On August 1, 2024, Vipin Narang, a senior Pentagon official, remarked, "We now find ourselves in nothing short of a new nuclear age." He attributed this development to an "unprecedented mix of multiple revisionist nuclear challengers who are uninterested in arms control or risk-reduction efforts, each rapidly modernizing and expanding their nuclear arsenals." == Anti-nuclear movement ==

A large anti-nuclear demonstration was held on 6 May 1979, in Washington D.C., when 125,000 people including the governor of California, attended a march and rally against nuclear power. In New York City on 23 September 1979, almost 200,000 people attended a protest against nuclear power. Anti-nuclear power protests preceded the shutdown of the Shoreham, Yankee Rowe, Millstone I, Rancho Seco, Maine Yankee, and about a dozen other nuclear power plants. On 12 June 1982, one million people demonstrated in New York City's Central Park against nuclear weapons and for an end to the Cold War arms race. It was the largest anti-nuclear protest and the largest political demonstration in American history. International Day of Nuclear Disarmament protests were held on 20 June 1983, at 50 sites across the United States. In 1986, hundreds of people walked from Los Angeles to Washington, D.C., in the Great Peace March for Global Nuclear Disarmament. There were many Nevada Desert Experience protests and peace camps at the Nevada Test Site during the 1980s and 1990s. On May 1, 2005, 40,000 anti-nuclear/anti-war protesters marched past the United Nations in New York, 60 years after the atomic bombings of Hiroshima and Nagasaki. This was the largest anti-nuclear rally in the U.S. for several decades. == Timeline ==

Other than the Chernobyl disaster, it is the only nuclear accident to be rated at level 7, the highest level on the scale, and caused the most dramatic shift in nuclear policy to date. == Influence on popular culture ==

• 1945 – The Atomaton chapter of Sweet Adelines was formed by Edna Mae Anderson after she and her sister singers decided, "We have an atom of an idea and a ton of energy." The name also recognized the Atomic Age—just three days after Sweet Adelines was founded (13 July 1945), the first nuclear bomb, Trinity, was detonated. • 5 July 1946 – The bikini swimsuit, named after Bikini Atoll, where an atomic bomb test called Operation Crossroads had taken place a few days earlier on 1 July 1946, was introduced at a fashion show in Paris. • 1954 – Them!, a science fiction film about humanity's battle with a nest of giant mutant ants, was one of the first of the "nuclear monster" movies. • 1954 – The science fiction film Godzilla was released, about an iconic fictional monster that is a gigantic irradiated dinosaur, transformed from the fallout of a hydrogen bomb test. • 23 January 1957 – Walt Disney Productions released the film "Our Friend the Atom" describing the marvelous benefits of atomic power. As well as being presented as an episode on the TV show Disneyland, this film was also shown to almost all baby boomers in their public school auditoriums or their science classes and was instrumental in creating within that generation a mostly favorable attitude toward nuclear power. • 1958 –The peace symbol was designed for the British nuclear disarmament movement by Gerald Holtom. • 1959 – The popular film On the Beach shows the last remnants of humanity in Australia awaiting the end of the human race after a nuclear war. • 1964 – The film Dr. Strangelove, or: How I Learned to Stop Worrying and Love the Bomb (aka Dr. Strangelove), a black comedy directed by Stanley Kubrick about an accidentally triggered nuclear war, was released. • 1982 – The documentary film The Atomic Cafe, detailing society's attitudes toward the atomic bomb in the early Atomic Age, debuted to widespread acclaim. • 1982 – Jonathan Schell's book Fate of the Earth, about the consequences of nuclear war, is published. The book "forces even the most reluctant person to confront the unthinkable: the destruction of humanity and possibly most life on Earth". The best-selling book instigated the Nuclear Freeze campaign. • 20 November 1983 – The Day After, an American television movie was aired on the ABC Television Network and in the Soviet Union. The film portrays a fictional nuclear war between the United States/NATO and the Soviet Union/Warsaw Pact. After the film, a panel discussion was presented in which Carl Sagan suggested that we need to reduce the number of nuclear weapons as a matter of "planetary hygiene". This film was seen by over 100,000,000 people and was instrumental in greatly increasing public support for the Nuclear Freeze campaign. == See also ==
