title: Alternative treaty monitoring approaches using ultra-low background measurement technology.
abstract: The International Monitoring System (IMS) of the Comprehensive Test Ban Treaty includes a network of stations and laboratories for collection and analysis of radioactive aerosols. Alternative approaches to IMS operations are considered as a method of enhancing treaty verification. Ultra-low background (ULB) detection promises the possibility of improvements to IMS minimum detectable activities (MDAs) well below the current approach, requiring MDA < or = 30 microBq/m(3) of air for (140)Ba, or about 10(6) fissions per daily sample.
