• Its main goal was to prohibit nuclear weapons tests or any other nuclear explosion in the atmosphere, outer space, and underwater.
• It allowed underground nuclear tests, provided they did not cause radioactive debris to be present outside the territorial limits of the state conducting the test.

Additional Information on Nuclear Test Ban Treaties

The Limited Test Ban Treaty was an important step towards controlling the nuclear arms race and reducing the environmental impact of nuclear testing. However, it did not ban all nuclear tests, as underground tests were still permitted. This led to further efforts towards a comprehensive ban.

• The treaty encouraged many other countries to sign and adhere to its provisions.
• It helped to reduce the levels of radioactive particles in the atmosphere.
• Efforts continued over the decades to achieve a Comprehensive Nuclear-Test-Ban Treaty (CTBT), which would ban all nuclear tests, including underground ones. The CTBT was adopted in 1996 but has not yet entered into force due to a lack of ratification by certain key states.
