The organization will be tasked with verifying the ban on nuclear tests and will operate therefore a worldwide monitoring system and may conduct on-site inspections.
[1] The organization's scientific reporting claims 2.4 million persons will eventually die from cancers developed as a result of atmospheric atomic tests conducted between 1945 and 1980.
[3] States Parties to the Treaty are encouraged to conduct a Consultation and Clarification process (C&C) before requesting an on-site inspection.
If an event detected by the IMS (or by other means) raises concerns about violation of the basic obligations of the CTBT, an OSI may be conducted to clarify whether a nuclear explosion has taken place.
Such an inspection could take place only after entry into force of the Treaty, and would require agreement by at least 30 of the 51 members of the CTBTO's Executive Council.
This requires States Parties to the treaty to notify the Organization, if possible in advance, of any chemical explosion using 300 tonnes or greater of TNT-equivalent blasting material to be detonated.
