Description
The CTBTO operates a worldwide network based on four complementary verification methods to detect any sign of a nuclear explosion conducted anywhere – underground, underwater or in the atmosphere. The radionuclide technology is the only one that can confirm whether an event is indicative of a potential nuclear test.
The four CTBT-relevant radioxenon isotopes are fission products. They are measured by stations equipped with noble gas capabilities and play a crucial role when determining whether an event is of CTBT-relevance. Specific measurement systems have been designed in the past decades to match the needs of the network using state-of-the-art technologies. In parallel, tailored analysis methods have been developed and implemented by the International Data Centre to make radioxenon measurement data more and more relevant for CTBT-purposes.
This is a complex task, as a highly variable radioxenon background produced by civil nuclear facilities is likely to interfere with the potential signal of a nuclear explosion, making the identification of CTBT-specific events a challenging task.
This work intends to provide an overview of 15 years radioxenon monitoring by the CTBTO. Current challenges are also presented, together with the potential of further advancing knowledge and understanding of the radioxenon background.
