Nuclear tourism is travel to places connected with nuclear research and technology, places where there have been atomic explosions, or places related to peaceful or wartime use of nuclear energy. They include:
- Sites of nuclear explosions (bombed cities, weapon test sites, sites related to peaceful use of nuclear explosions)
- Sites of nuclear accidents and accidents of nuclear weapon carrying aircraft
- Atomic museums
- Otherwise remarkable sites of projects in nuclear technology
Although in many of the nuclear tourism sites only background radiation can be detected, in some other visitors are confronted with levels above natural background. 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 a 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 in order to evaluate the information obtained from the counter. Also one has to be aware of a strong variation of natural background radiation, which depends mainly on local geology.
Sites of nuclear explosions
Hiroshima, 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 in Hiroshima Peace Memorial Park, including the iconic A-Bomb Dome or Children's Peace Monument covered by colorful paper cranes for bomb victim, Sadako Sasaki.
Another nuclear bomb was dropped three days later on the industrial town of Nagasaki, Japan, with more than 60,000-80,000 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 located near ground zero.
Weapon test sites
- Trinity site, New Mexico - the site of the world's first nuclear explosion on July 16, 1945, which started the Atomic age. The site, which was declared a National Historic Landmark district, is open for tours once in a year (first Saturday in April). The ground zero, where the plutonium bomb was detonated from a tower, is marked with a plain stone monument. Careful visitors can spot glassy greeny pieces in the dirt. It is "Trinitite", sand fused by the enormous heat of the explosion into a crusty surface. Most of Trinitite was cleared away in the years after the test with a small piece of original surface preserved in a shelter. The small fractions of Trinitite left at the site do not pose any health hazard to the visitors from the external exposure point of view, but it is not allowed to take away any Trinitite from the inner fenced area. During the Trinity site open house days it is also possible to view Schmidt/McDonald ranch house, where the plutonium core to the bomb was assembled shortly before the test.

Sites of nuclear accidents
While some might find it unethical or at least controversial visiting sites where many people suffered following an accident as a tourist, the locals on the other hand welcome tourism as alternative means to support local economies.
Accidents in nuclear power plants or nuclear materials production sites
- Pripyat, Chornobyl Oblast, Ukraine. The Chernobyl disaster happened on the 26 April 1986. It is an event classified at level 7 on the International Nuclear Event Scale. Although the Chernobyl sarcophagus was constructed with lots of concrete and by 500k workers the structure has since deteriorated and crumbled. There are plans to fix the containment by 2015.
- Sellafield is site of a number of accidents including the 1957 fire of the former nuclear reactor Windscale. It has been host to a number of reprocessing operations (2005 leak) - during those accidents a lot of radioactive waste ended up in the Irish sea, near Whitehaven, United Kingdom
- Three Mile Island, near Hershey, Pennsylvania, United States of America
- Fukushima Daiichi nuclear power plant, Japan - damaged by 2011 tsunami
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 Faro 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 crater 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, 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 museum in Florence (expected to be re-opened after moving in Fall 2014) 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 Palomares between Almería and Cartagena, Spain. Nowadays, after cleanup operations, the area is used extensively for agricultural production. Two of the "hot areas" are closed to the public by a fence.

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.

Nuclear power plant building sites never finished
Some nuclear power plants never had a nuclear fission reaction happening on their site, as they were not turned on.
- Bataan Nuclear Power Plant. The Philippine's only attempt to build a nuclear power plant, this US$2.3 billion plant was completed in 1984, at which point testing of systems began. In 1986, the authoritarian government behind the project was overthrown and following the Chernobyl disaster later that year, the new government decided to mothball the plant. The Bataan Nuclear Power Plant is complete and has been maintained since then, but was never fueled to operate. All uranium was removed by 1997. Due to the high cost of maintaining the plant, the Philippine government announced in 2011 that the plant would be turned into a tourist attraction. The tour admission fee also includes use of the adjacent private beach, WestNuk Cove, which also has some accommodation and recreation facilities (Westnuk Beach Resort, ). 150 pesos (2012).

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 one mile (1.6km) 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.

The restored fishing boat Lucky Dragon which crew became unfortunate victims of nuclear fallout fallowing a thermonuclear test at Bikini Atoll is on display at Tokyo Metropolitan Daigo Fukuryū Maru Exhibition Hall. On 1 March 1954, 23 fishermen were hunting tuna near the Marshall Islands, when they witnessed the larger than predicted Castle Bravo nuclear test conducted by the US. Later on the fishermen were subjected to a strange white rain containing particles of radioactive fallout mixed with the coral reef debris. Unaware of the danger of the contamination on their bodies and the ship's surfaces, the fishermen headed back to Japan and over the following days developed symptoms of acute radiation syndrome. One crew member died later in hospital. Free.
- A Memorial to the X-ray martyrs of the world in Hamburg (Ehrenmal der Radiologie) (Garden of St. Georg hospital). This monument is devoted to researchers, physicians, physicists, radiographers, laboratory technicians and nurses who died from injuries or illnesses caused by prolonged exposure to radiation used in medicine. On the list of about 360 names of radiologists from 23 countries perhaps the best known are Marie Sklodowska-Curie and her daughter Irène Joliot-Curie.
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 probably 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 USA. 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 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 limit the distance to 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.
Another kind of more general risks can arise from exploration of abandoned and off-limits urban locations. These include injuries or possible legal consequences. For more details check Urbex article.
