Nuclear-free zones usually neither address nor prohibit radiopharmaceuticals used in nuclear medicine even though many of them are produced in nuclear reactors. They typically do not prohibit other nuclear technologies such as cyclotrons used in particle physics.
Several sub-national authorities worldwide have declared themselves "nuclear-free". However, the label is often symbolic, as nuclear policy is usually determined and regulated at higher levels of government: nuclear weapons and components may traverse nuclear-free zones via military transport without the knowledge or consent of local authorities which had declared nuclear-free zones.
Palau became the first nuclear-free nation in 1980.  New Zealand was the first Western-allied nation to legislate towards a national nuclear free zone by effectively renouncing the nuclear deterrent.

Many Australian local government areas of Australia have passed anti-nuclear weaponry legislation; notable among these are Brisbane, capital of Queensland, which has been nuclear weapon free since 1983, and the South and North Sydney councils. However the passage of such legislation is generally considered just a symbolic measure.  The majority of councils which have passed anti-nuclear weaponry legislation are members of the Australian Nuclear Free Zones and Toxic Industries Secretariat which has 44 member councils. 
Austria is a nuclear free zone, when a nuclear power station was built during the 1970s at Zwentendorf, Austria, start-up was prevented by a popular vote in 1978. The completed power plant is now marketed as a shooting location for film and television.  On July 9, 1997, the Austrian Parliament voted unanimously to maintain the country's anti-nuclear policy. 
Ironically, the headquarters of the International Atomic Energy Agency is located in Vienna, and the IAEA maintains nuclear laboratories both in Vienna and Seibersdorf.  The IAEA has also established programs to assist nuclear energy projects in developing countries.
Austria's anti-nuclear stance also causes tension with its nuclear neighbors. Vienna is located close to the Czech reactor at Temelin, and four reactors are being built in neighboring Slovakia and two in neighboring Hungary.  Austria also draws from regional electricity grids, meaning it imports nuclear power, although chancellor Werner Faymann has pledged to eliminate Austria's reliance on foreign power by 2015. 
Vancouver is a nuclear weapons free city.  Victoria, British Columbia is also a nuclear weapons free city. This has caused problems as nearby Esquimalt houses CFB Esquimalt, Canada's Pacific naval base, which is used frequently by the United States Navy. The USN routinely sends ships or aircraft carriers loaded with nuclear weapons to Esquimalt. As a result, the ships are forced to dock out of the city limits as not to violate the city by-laws.[ citation needed]The policy does not limit operations at TRIUMF, Canada's national laboratory for nuclear and particle physics at the University of British Columbia, Vancouver. The province of British Columbia also bans mining for uranium, and the construction of nuclear power plants within its territorial limits.

All states of Central Asia have signed the Treaty on the Non-Proliferation of Nuclear Weapons and signed the Central Asian Nuclear Weapon Free Zone treaty. Thus, there are no technologies to create a weapon or enrich the particles, but in Tajikistan, during the Soviet Union, such initiatives were brought to life, but with the collapse of the Soviet Union, the facilities were dismantled and moved to the Russian Federation. The Treaty came into force on 21 March 2009.

After Estonia seceded from the Soviet Union in the early 1990s, Estonia became a nuclear-free country. The two land-based nuclear reactors at the Soviet Navy nuclear submarine training centre in Paldiski were removed when Russia finally relinquished control of the nuclear reactor facilities in September 1995. There are no nuclear power stations in Estonia.
As a resource-poor nation, Japan is heavily reliant on nuclear power, but its unique experience in World War II has led to the wholesale rejection of nuclear weapons, holding nuclear weapons shall not be manufactured in, possessed by, or allowed entry into Japan. These tenets, known as the Three Non-Nuclear Principles, were first stated by Prime Minister Eisaku Satō in 1967, and were adopted as a parliamentary resolution in 1971, though they have never formally been entered into law. They continue to reflect the attitudes of both government and the general public, who remain staunchly opposed to the manufacture or use of nuclear weapons.
The Japan Self-Defense Forces have never made any attempt to manufacture or otherwise obtain nuclear arms, and no nuclear weapons are known to have been introduced into the Japanese Home Islands since the end of World War II. While the United States does not maintain nuclear bases within its military installations on the Home Islands, it is believed to have once stored weapons at Okinawa, which remained under US administrative jurisdiction until 1972.
Italy is a nuclear free zone since the Italian nuclear power referendum of November 1987. Following center-right parties' victory in the 2008 election, Italy's industry minister announced that the government scheduled the construction to start the first new Italian nuclear-powered plant by 2013. The announced project was paused in March 2011, after the Japanese earthquake, and scrapped after a referendum on 12–13 June 2011.
In 1984, Prime Minister David Lange barred nuclear-powered or nuclear-armed ships from using New Zealand ports or entering New Zealand waters. Under the New Zealand Nuclear Free Zone, Disarmament, and Arms Control Act 1987,   territorial sea and land of New Zealand became nuclear weapons and nuclear-powered ship free zones. It does not ban nuclear power stations. A research reactor was operated by the University of Canterbury until 1981. Official planning for a nuclear power station continued until the 1980s. A nuclear reactor provided electricity for McMurdo Station, in the New Zealand Antarctic Territory from 1962–1972.
The Act prohibits "entry into the internal waters of New Zealand 12 miles (22.2 km) radius by any ship whose propulsion is wholly or partly dependent on nuclear power" and bans the dumping of radioactive waste within the nuclear-free zone, as well as prohibiting any New Zealand citizen or resident "to manufacture, acquire, possess, or have any control over any nuclear explosive device."   Combined with the firm policy of the United States to "neither confirm nor deny" whether particular naval vessels carry nuclear weapons, the Act effectively bars these ships from entering New Zealand waters. 
New Zealand's security treaty with the United States, ANZUS, did not mention nuclear deterrence and did not require unconditional port access. However, after New Zealand refused entry to USS Buchanan, the United States government suspended its ANZUS obligations to New Zealand, seeing New Zealand's effective rejection of United States Navy vessels as voiding the treaty. The Lange Labour government did not see their stance as incompatible with the treaty and sought a compromise for over two years before passing the Act.  Support for the non-nuclear policy was bolstered by the perceived over-reaction of the United States and by the sinking of the Rainbow Warrior by French spies while docked in Auckland. According to some commentators, the legislation was a milestone in New Zealand's development as a nation and seen as an important act of sovereignty, self-determination and cultural identity.   New Zealand’s three decade anti-nuclear campaign is the only successful movement of its type in the world which resulted in the nation's nuclear-free zone status being enshrined in legislation. 
The nuclear-free zone law does not make building land-based nuclear power plants illegal. However, the relatively small electricity system, abundance of other resources to generate electricity, and public opposition has meant a nuclear power plant has never gone beyond the investigation phase – a nuclear power plant was proposed north of Auckland in the early 1970s, but the discovery of large natural gas reserves in Taranaki saw the proposal shelved.

Nuclear weapons-free Nordic (Finn. Ydinaseeton Pohjola) was an initiative by the President of Finland Urho Kekkonen for a nuclear weapons-free zone in the Nordic countries. The aim was to prevent the Nordic countries from becoming a nuclear battleground and a route for cruise missiles in the event of a nuclear war between the Soviet Union and NATO.
Palau adopted its first constitution in July 1979, stating that the Micronesian country would be "nuclear-free". The United States told the Palauan government that this constitution was likely incompatible with the Compact of Free Association. The Palauan government submitted a revised version of the constitution without the "nuclear-free" clause the following October. The Palauan people rejected the revised document and instated the original constitution in July 1980.  Seven years later, however, the Palauan people voted to overturn their nuclear-free status out of "economic survival". 
The Nuclear Free Zone Movement in the United Kingdom was very strong in early 1980s; up to two hundred local authorities including county councils, district councils and city councils such as the Greater London Council (GLC) (before its abolition) declared themselves to be 'nuclear free'. The first 'nuclear-free zone' in the UK was Manchester City Council in 1980 – this still exists to this day. Wales became 'nuclear free' on 23 February 1982 after Clwyd County Council declared itself 'nuclear free' and the Nuclear Free Wales Declaration was made. This policy was legally underpinned by Section 137 of the Local Government Act, which allowed local authorities to spend a small amount on whatever members considered was in the interest of their area or a part of their area.
UK nuclear-free local authorities refused to take part in civil defence exercises relating to nuclear war, which they thought were futile. The non-cooperation of the nuclear-free zone authorities was the main reason for the cancellation of the national 'Hard Rock' civil defence exercise in July 1982. In England and Wales 24 of the 54 county councils refused to participate and seven more co-operated only in a half-hearted way.  This has been seen as a victory for the British Peace movement against the policies of Margaret Thatcher. Generally, nuclear-free zones were predominantly Labour Party controlled councils but Liberal Party and even a few Conservative Party councillors were often active in this respect too.
A number of towns, cities and counties in the United States established themselves as Nuclear-Free Zones in the 1970s, 1980s and 1990s. The first was Missoula, Montana. In the November 1978 general election, Missoula voters overwhelmingly approved a ballot initiative in the form of a land-use ordinance establishing the entirety of Missoula County as a "'nuclear free' zoning district" banning all nuclear facilities except those for medical purposes. (In the same election, Montana voters approved a statewide initiative by a 2–1 margin barring nuclear facilities or reactors without strict state-enforced regulatory standards and ratification by popular referendum, and in a follow-up 1980 initiative, Montanans narrowly voted to ban the disposal of nuclear waste.) That Missoula's measure was originally drafted as a zoning ordinance legally enforceable by the county planning department apparently created the popular term "Nuclear Free Zone" adopted as the name of the local political action group sponsoring the initiative and later used by other jurisdictions worldwide. 
Subsequently, the tiny town of Garrett Park, Maryland, attracted worldwide attention with its referendum in May, 1982. The following year, Takoma Park, Maryland, was officially declared a nuclear-free zone in 1983 by then-mayor Sam Abbott. A citizen committee of the local city council continues to monitor city contracts. The city cannot hold contracts with any company associated with any aspect of nuclear weapons without a waiver from the citizen committee. In September 2005, Takoma Park took a stand against the transportation of high-level nuclear waste through the City. It voted to amend its Nuclear-Free Zone Ordinance to give its citizen committee responsibility to collect information and from this information and from consultations with individuals and organizations involved in the transportation of high-level nuclear waste, to advise the City on how to promote the safety and welfare of its citizens from harmful exposure to high-level nuclear waste. 
Another well-known nuclear-free community is Berkeley, California, whose citizens passed the Nuclear Free Berkeley Act in 1986 which allows the city to levy fines for nuclear weapons-related activity and to boycott companies involved in the United States nuclear infrastructure. The City of Berkeley has posted signs at city limits proclaiming its nuclear free status. The ordinance specifies possible fines for such activities within its borders. The University of California, Berkeley is deeply involved in the history of nuclear weapons, and the University of California system until recently managed operations at Los Alamos National Laboratory, a U.S. nuclear weapons design laboratory, and continues to manage the Lawrence Livermore National Laboratory. At the time of the passage of the act, the University operated a nuclear reactor for research purposes, the Etcheverry Reactor, which it continued to operate after the act went into effect. The University of California, as a state institution, is not subject to Berkeley's municipal regulations, including the ban. Berkeley also has major freeway and train lines which are used in transporting nuclear materials.
On November 14, 1984 the Davis, California City Council declared the city to be a nuclear-free zone.  Davis has major freeway and train arteries running through it which are used for transporting nuclear materials. The University of California, with a campus at Davis, runs a research reactor at the nearby former McClellan Air Force Base, as well as workers who are involved with Lawrence Livermore National Laboratory.
On November 8, 1988 the city of Oakland, California passed "Measure T" with 57% of the vote, making that city a nuclear free zone. Under Ordinance No. 11062 CMS then passed on December 6, 1988, the city is restricted from doing business with "any entity knowingly engaged in nuclear weapons work and any of its agents, subsidiaries or affiliates which are engaged in nuclear weapons work."  The measure was invalidated in federal court, on the grounds that it interfered with the Federal Government's constitutional authority over national defense and atomic energy.   The issue being Oakland is a major port, and like Berkeley, and Davis, has major freeway and train arteries running through it. In 1992, the Oakland City Council unanimously reinstated modified elements of the older ordinance, reportedly bringing the total number of Nuclear Free Zones in the United States at that time to 188, with a total population of over 17 million in 27 states.
