Nuclear tourism

Nuclear tourism is travel to places connected with nuclear history, nuclear science, and nuclear technology. This can include historical sites of nuclear detonations or places related to peaceful or wartime use of nuclear energy.

Sites of interest to the nuclear tourist may include:
 * Sites of nuclear detonations (bombed cities, nuclear weapons tests, sites related to peaceful uses of nuclear explosives).
 * Sites of nuclear accidents and accidents of aircraft carrying nuclear weapons.
 * Museums of nuclear history, nuclear science, or nuclear technology.
 * Former nuclear missile silos and nuclear fallout shelters.
 * Other sites relating to nuclear history, nuclear science, and nuclear technology (for example, nuclear particle accelerators and sites of nuclear physics research).

"I know not with what weapons World War III will be fought, but World War IV will be fought with sticks and stones."

- Albert Einstein

See Golden Age of Modern Physics for the discoveries that led up to the atomic age.

Although in many of the nuclear tourism sites only background radiation can be detected, in some other visitors are confronted with higher levels. These include mainly sites related to nuclear accidents and weapons testing. When visiting places with increased radiation, it is reasonable to be equipped with a radiation monitor in order to have control over radiation exposure. The most common devices in a reasonable price range usually contain a Geiger-Müller counter. They are suitable for detection of gamma, x-ray, alpha and beta radiation, typically expressed as counts per second. In other devices the registered gamma radiation is converted in units of dose rate or absorbed dose. These basic counters can not provide information about individual isotopes, natural or man-made, but simply sum up all registered radiation.

In order to be able to use the radiation monitor it is essential to get familiar with the units and ranges of the measured values to evaluate the information obtained from the counter. Additionally, one has to be aware of a strong variation of natural background radiation, which depends mainly on local geology.

Bombed cities
, Japan, was a target of the first nuclear attack ever on 6 August 1945. Nowadays the event with 90,000–166,000 civilian victims is commemorated at the Atomic Bomb Memorial Museum and in Peace Memorial Park, including the iconic A-Bomb Dome and Children's Peace Monument covered by colorful paper cranes for bomb victim, Sadako Sasaki. Ground Zero is slightly outside of the park not far from the Atomic Bomb Dome.

Another nuclear bomb was dropped three days later on the industrial town of, Japan, with more than 100,000 victims. Visitors can learn about the tragic piece of history in the Nagasaki Atomic Bomb Museum or the Nagasaki National Peace Memorial Hall for the Atomic Bomb Victims, both near ground zero.

The aircraft that dropped nuclear weapons on Japanese civilians are in US museums. Enola Gay (the plane which bombed Hiroshima) is displayed at the Udvar-Hazy Center (part of Smithsonian's National Air and Space Museum) in Chantilly, Virginia ; Bockscar (which bombed Nagasaki) is on display at the U.S. Air Force Museum near Dayton, Ohio.

See the Pacific War article for the events leading up to the bombs.

Weapon test sites
Eight countries have carried out confirmed nuclear weapon tests to determine the capability of their weapons, mostly in their own respective territories. The United States conducted the first and the most numerous tests, mostly in Nevada. Others carrying out tests included Russia (then the Soviet Union), the UK, India, France, and China. Pakistan, followed by North Korea, conducted the last nuclear weapon tests. Sites where weapon tests were conducted can be visited in these countries for adventure.




 * Atolls and  are former US test sites at Marshall Islands. They are in the middle of the Pacific, far away from any mainland, so they are difficult to visit. Bikini Atoll is open for tourism from late April to November and welcomes divers participating in organized tours. These tours that start at Kwajalein Atoll are only available to experienced divers and the main attraction is the U.S. fleet sunk by the nuclear tests at Bikini. In the 1970s the U.S. Army performed a clean-up of contamination at Enewetak. As a result, radioactive materials from Enewetak and other contaminated atolls were dumped into the Cactus test crater at a tiny island Runit within the Enewetak Atoll and covered by a concrete structure, known as Cactus dome.







Peaceful use of nuclear explosions
In the USA, 27 peaceful nuclear explosions were conducted within Operation Plowshare to test the use of nuclear explosions for various civilian purposes, such as excavating channels or harbors and stimulating natural gas production from sediment layers. Most of the shots were performed at the Nevada test site; however, some of the test sites in Colorado and New Mexico are accessible for the public.







Sites of nuclear accidents
Some might find it unethical or at least controversial for tourists to visit sites where many people suffered following an accident, especially if local guides are repeatedly exposed to radiation when leading tour groups through exclusion zones too "hot" for residents to return.

Conversely, some welcome tourism as an alternative means to support local economies.

Accidents in nuclear power plants or nuclear materials production sites



 * , United Kingdom, has been the site of a number of accidents, including the 1957 fire of the original Windscale former nuclear reactor. During those accidents some radioactive waste ended up in the Irish Sea, near Whitehaven. Also, during the reactor fire radioactivity was released through the chimney. However the major portion was contained by the high-capacity filters mounted on the chimney (known as "Cockcroft's Folly" after the Nobel prize winning physicist Sir John Cockcroft, who insisted on having them mounted at great expense, although they hadn't been included in the original design. Their shape contributed to the iconic silhouette of the nuclear complex. However, in 2014 the second of two chimneys was decommissioned and is no longer part of the Sellafield skyline.)
 * The nuclear site has been hosting a number of nuclear reprocessing operations. There used to be a visitors' centre, but it is no longer open.
 * When spending time on nearby beaches (for example the one in Seascale), you might be lucky enough to spot the Sellafield environmental monitoring workers beachcombing for "hot particles" using a special all-terrain vehicle.


 * , near Harrisburg, Pennsylvania, USA, was the worst commercial nuclear power plant accident in the USA on 28 March 1979. During the reactor core meltdown, radioactivity, mainly in the form of radioiodine and noble gases, was released to the surrounding environment. There is no visitors' center commemorating the event, only a historic marker (at the given coordinates in Middletown) with a fine view across the Susquehanna river towards the power station.
 * in Japan was seriously damaged by a tsunami following a magnitude 9 earthquake on March 11, 2011. Large areas of Fukushima prefecture coast are being decontaminated, while some 80,000 inhabitants had to be resettled. Tours are offered to the visitors to get first-hand impressions from areas affected by the great Tohoku earthquake, tsunami, and nuclear accident. The participants can experience how local people and businesses are coping with the recovery from the disasters.

Accidents of nuclear weapon carrying aircraft
During the Cold War there were several accidents involving thermonuclear weapons, and some of them led to local environment contamination. These are a few of them.
 * In near Goldsboro (North Carolina), USA, a B-52 crash dropped a hydrogen bomb which failed to detonate in 1961. The event is commemorated by a historical road marker in the town of Eureka, 3 miles (4.8 km) north of the crash site.
 * A about 23 m wide and 11 m deep was left after another accident, in which a B-47 "Stratojet" crew mistakenly released a Mark 6 bomb while flying over Mars Bluff, South Carolina, USA, on March 11, 1958 afternoon. The bomb went off by a conventional explosion at the property of local family Gregg and injured several family members. The crater can be visited from SC Highway 76 (East Palmetto Street) via a marked trail. There is an informational board and mock up of the bomb's size at the site. Nearby  in Florence has the story to tell including some historical artifacts connected to the event.
 * In 1966 after an unsuccessful inflight refueling operation an US bomber B-52 carrying four hydrogen bombs crashed in between Almería and Cartagena, Spain. Now, after cleanup operations, the area is used extensively for agricultural production. Two of the "hot areas" are closed to the public by a fence.
 * Another accident occurred in 1968, when B-52 "Stratofortress" with four hydrogen bombs on board crashed onto the sea ice near the, Greenland. The nearest civilian settlement is Qaanaaq, 100 km to the north.

Manhattan Project-related sites
"We knew the world would not be the same. A few people laughed... A few people cried... Most people were silent. I remembered the line from the Hindu scripture the Bhagavad Gita; Vishnu is trying to persuade the prince that he should do his duty, and to impress him takes on his multi-armed form, and says, Now I am become death, the destroyer of worlds. I suppose we all thought that, one way or another."

- Robert Oppenheimer recalling the Trinity bomb

"Manhattan Project", named for the Manhattan Engineering District of the US Army Corps of Engineers, is a cover name for a war-time US military effort to develop an atomic weapon. Geographically, the project was spread over about 30 sites across the United States (and Canada). The best known are the secret laboratory in Los Alamos and factories to supply the fissile materials by enriching uranium and producing plutonium in reactors in Oak Ridge, Tennessee, and Hanford site near Richland, Washington. These three sites are also formally recognized as Manhattan Project National Historical Park.









Atomic museums

 * A three-hour-long guided bus tour departs from the museum on some working days in summer season (March to November, for detailed schedule check the AMSE webpage). The tour takes visitors to the U.S. Department of Energy facilities: Y-12 (Uranium enrichment plant) Visitor Center or Oak Ridge National Laboratory Graphite Reactor, also known as . It was the second nuclear reactor after Enrico Fermi's Chicago pile, now the world’s oldest nuclear reactor preserved as national historic landmark. X-10 was the first nuclear reactor to produce Plutonium 239 within the Manhattan Project. Only U.S. citizens can join the tour.

Research reactors
Several sites operate nuclear reactors for either nuclear reactor safety training or for nuclear science experiments using them as neutron sources. Neutron scattering is an effective ways to obtain information on the structure and the dynamics of condensed matter. These days accelerators like the Spallation Neutron Source based in Oakridge allow more intense neutron beams. Nevertheless several reactors are in on-going operations. Fundamental and solid state physics, chemistry, materials science, biology, medicine and environmental science pose scientific questions that are investigated with neutrons.

In contrast to nuclear fission, where unstable atoms decay into smaller atoms, there exists also an attempt of nuclear fusion, where energy would be gained by processes similarly to what happens in the core of stars by the fusion of two light elements in a heavier one. ITER is an international nuclear research and engineering project to build the first the world's largest experimental tokamak nuclear fusion reactor.

Sites related to German nuclear bomb project
Germany, which had had some leading nuclear scientists before the war (some of whom fled the country after the Nazi takeover due to being Jewish, opposed to the regime or both), developed a much more modest and less advanced nuclear program than the Allies. It received less funding and was hampered by Nazi ideology which rejected some of Albert Einstein's findings as "Jewish Physics", but its speculated existence during the war was one of the driving factors for the Manhattan project.
 * Heavy water production site and location of war-time heavy water sabotage. Heavy water is an important component in certain nuclear applications and was seen as critically necessary for the development of a nuclear bomb during World War II. Despite the German occupation of Norway, Norwegian underground fighters ultimately managed to keep the heavy water out of the hand of the Nazis, thereby delaying the nuclear program of Nazi Germany which failed.

Nuclear bunkers
Nuclear bunkers were meant to protect in the case of nuclear weapon explosions. During the cold war this threat was considered imminent, hence many key figures would need access to such bunkers. While nothing was likely to withstand a direct hit, bunkers were built far underground to survive a nuclear strike which landed as close as 1 mile (1.6 km) away.

Fallout shelters were intended to shelter populations in areas far from the targets of a nuclear strike; these communities were likely to be spared direct blast damage but still become dangerously radioactive in the initial days or weeks after an attack. Often, civil defence authorities would make provision for a posted fallout shelter in the basement of a library, post office, school or other large public building. In some countries building regulations even pushed for bunkers in the cellars of small domestic buildings.





Nuclear weapon sites








Nuclear waste related sites
Nuclear waste is a big headache in all nuclear applications as it remains dangerous for timespans humans cannot generally oversee. There are various philosophies as to what to do with the waste, including putting it into abandoned salt mines as salt has high stability to waste heat (nuclear waste produces a lot of heat) and salt tends to naturally seal cavities. However, salt is vulnerable to water entering and there is the danger of that water connecting to groundwater, as has happened at several salt mines.

Stay safe
One obvious concern in touring nuclear sites is radiation. In fact, good news is that most of the sites listed above are safe from this point of view. Where obvious danger exists, you should be usually stopped by fence and other security measures.

In case you happen to find yourself in a less safe situation or unknown suspicious area, you will hopefully be equipped with a radiation monitor and good knowledge of how to use it. It's important to know how to interpret the readings and/or convert the units. Although officially there is nothing like a safe level or radiation, there are some levels that can help to put the numbers into context. These are some examples:
 * The typical yearly dose from purely natural background, consisting mainly of radon gas we breathe, building materials surrounding us, radionuclides in food we eat and from the cosmic radiation that keeps bombarding us. This value is 2.4 thousandths of Sievert (mSv) on average, with a large range between 1–13 mSv depending mainly on the geological background of the place you live.
 * Additionally to natural sources, artificial radiation contributes to radiation exposure of some of us. The main contributor here is medical diagnosis and treatment using radiation or radionuclides. Here the exposition varies widely based on number and type of such measures. Globally, an average person receives 0.6 mSv/yr, while in countries with well developed medical systems the numbers are higher, for example 3.14 mSv in the USA, which relies heavily on testing like CT scans and X-rays. One bone scintigraphy scan with the use of medial isotope Tc-99m results in a one-time dose of about 5 mSv. A chest CT scan can give a dose of 5–10 mSv, which is much higher than a simple chest x-ray of 0.2 mSv.
 * Members of flight crews receive some 1.5 mSv annual dose due to increased cosmic radiation in high altitudes.
 * The limit for members of the public in the Fukushima exclusion zone was set as 20 mSv/yr.
 * Occupational limits for radiation workers are usually at 50 mSv/yr.

The way to protect yourself against external radiation exposure (like radiation coming from soil polluted with radioactive fallout) is to limit the time spent in the polluted area and keep your distance from the source (hot spots).

During your exploration you certainly want to avoid internal contamination, that means ingesting radionuclides by eating or drinking contaminated food, or inhaling radioactive particles. Some easy protective measures are therefore avoiding eating and drinking and wearing a respirator. If there may be radioactive dust or water, you also want to avoid carrying that out from the area in your clothes or hair. Be sure to get clean before touching any food or anything that you will regard clean.

Another kind of more general risks can arise from exploration of abandoned or off-limits urban locations. These include injuries or possible legal consequences. For more details check the Urbex article.
