Speaker
Description
The radionuclide network of the International Monitoring System (IMS), operated by the Comprehensive Nuclear-Test-Ban Treaty (CTBT) Organization, is comprised of particulate and noble gas analysis. A variety of spectroscopic techniques have been developed and are in use to identify radionuclides which may be indicative of a nuclear explosion. Ongoing efforts to increase the sensitivity of measurements and reduce detection limits have seen the development of more advanced techniques. These include gamma-gamma coincidence spectroscopy to measure low level particulate samples and high resolution beta-gamma coincidence spectroscopy for radioxenon measurements. This poster will present a review of the latest published information on spectroscopic techniques in use and being developed in support of nuclear explosion monitoring.
Promotional text
Development of more sensitive techniques for radionuclide measurements mean it is possible to detect CTBT-relevant radionuclides at much lower activities. Such improvements in the sensitivity and selectivity of measurement systems can greatly improve the effectiveness of the IMS.
