Comprehensive atmospheric nuclear test

Atmospheric radioactivity is monitored globally for the verification of the Comprehensive Nuclear-Test-Ban Treaty (CTBT), with xenon isotopes Xe, Xe, Xe, and Xe serving as important indicators of nuclear explosions. The interpretation of atmospheric concentrations of radioxenon has been enhanced by quantifying radioxenon emissions released from... 

This industry is on the decline due to the peace-time agreements and Comprehensive Test Ban Treaty, (CTBT). Under this agreement, enrichment of UF6 is restricted to lower grade U235 for reactor fuel to be used in commercial electric power generation. In North America, there is an antinuclear atmosphere, hence it is less likely to see the expansion or additions of nuclear power plants in the USA. Whereas China, India, and East European countries may require additional nuclear fuel for their fast growing industries and electrification of the rural areas. 

A variety of on-site and remote sensor technologies can be used for verification of the Comprehensive Test Ban Treaty, with each offering unique sensing capabilities. The technologies can be used to search for nuclear explosions conducted in the atmosphere, underwater, underground, or outer space. The use of two or more sensors of different types increases the reliability of detection, and can help identify otherwise ambiguous events.
