Kärnvapenprovet

Kärnvapenprovet refers to the testing of nuclear weapons. These tests are conducted to develop, verify, or demonstrate the capabilities of nuclear weapons. Historically, nuclear-armed states have conducted atmospheric, underground, and underwater tests. The first nuclear weapon test, codenamed Trinity, was conducted by the United States in 1945. Following the development of nuclear weapons, several nations engaged in extensive testing programs throughout the mid-20th century.

These tests released significant amounts of radioactive fallout into the atmosphere, raising international concerns about their environmental and health impacts. This led to a growing movement advocating for the cessation of nuclear weapons testing. The Partial Test Ban Treaty, signed in 1963, prohibited nuclear weapon tests in the atmosphere, in outer space, and underwater. However, underground testing continued by some nations.

The Treaty Banning Nuclear Weapons Tests and Other Nuclear Explosions, also known as the Comprehensive Nuclear-Test-Ban Treaty (CTBT), was adopted by the United Nations General Assembly in 1996. While the CTBT has not officially entered into force, it represents a significant international norm against nuclear testing. Many countries have voluntarily adhered to its provisions, and only a few nations have conducted nuclear tests in recent decades. The pursuit of a world free from nuclear testing remains a key objective of international disarmament efforts.
