United Republic of Tanzania Signs and Ratifies the Comprehensive Nuclear-Test-Ban Treaty

Vienna, 1 October 2004: The United Republic of Tanzania has signed and ratified the Comprehensive Nuclear-Test-Ban Treaty (CTBT) on 30 September 2004, bringing the total number of Treaty ratifications to 119. The number of ratifying States in the Africa geographical region now stands at 26. In total, 173 States have signed the Treaty, with 50 of these signatures in the Africa region.

Tanzania hosts one International Monitoring System (IMS) facility: a radionuclide station, RN64, at Dar es Salaam. This station forms part of the global network of 337 IMS monitoring facilities being established under the terms of the CTBT to verify compliance with the terms of the Treaty. The monitoring facilities transmit data via satellite to the International Data Centre (IDC) in Vienna, where the data are used to detect, locate and characterize events. These data and IDC products are made available to the States Signatories for final analysis.

The CTBT bans all nuclear test explosions. Drafted at the Conference on Disarmament in Geneva, and adopted by the General Assembly on 10 September 1996, the Treaty was opened for signature eight years ago today, on 24 September 1996 at the United Nations headquarters in New York.

To enter into force, the CTBT must be signed and ratified by the 44 States listed in Annex 2 to the Treaty. These States formally participated in the work of the 1996 session of the Conference on Disarmament and possessed nuclear power or research reactors at that time. To date, 33 of the Annex 2 States have ratified the Treaty.
