Where We've Been
The Workshop on Signatures of Man-made Isotope Production Remote 2 (WOSMIP Remote 2) was held virtually May 25-27, 2021. WOSMIP Remote 2 discussed issues associated with the backgrounds of radionuclides of environment, stack measurements, emissions mitigation, atmospheric transport modeling, an update on the production of medical isotopes, research and development issues, and events of interest.
The seventh Workshop on Signatures of Man-Made Isotope Production (WOSMIP) was held in Sydney, Australia from December 3-7, 2018. The workshop was hosted by the Australian Nuclear Science and Technology Organization (ANTSO) and supported by the Pacific Northwest National Laboratory (PNNL).
The sixth Workshop on Signatures of Man-Made Isotope Production (WOSMIP) was held in San Carlos de Bariloche, Argentina from 28 November through 2 December, 2016. The focus of the workshop was to bring together representatives from the isotope production and nuclear explosion monitoring communities in order to discuss effects on the verification efforts for the Comprehensive Nuclear-Test-Ban Treaty (CTBT) resulting from nuclear facility radioxenon emissions.
The fifth Workshop on Signatures of Medical and Industrial Isotope Production (WOSMIP) was held in Brussels, Belgium on May 12-14, 2015. The focus of the workshop was to bring together representatives from the medical isotope production (MIP) and nuclear explosion monitoring communities to discuss ways to mitigate the effects of radioxenon emissions from fission-based MIP on the verification efforts for the Comprehensive Nuclear-Test-Ban Treaty (CTBT).
The fourth Workshop on Signatures of Medical and Industrial Isotope Production (WOSMIP IV) was held November 11-13, 2013, at the Vienna International Center in Vienna, Austria. The workshop brought together 82 experts from 25 countries from the isotope production and radionuclide nuclear explosion monitoring communities to continue discussions on the challenges for nuclear explosion monitoring presented by effluents from medical isotope production.
Radioactive xenon isotopes are produced by uranium fission in nuclear reactors and in nuclear-weapon explosions. Four xenon isotopes are produced in high yield and have sufficiently long half-lives to be useful in environmental monitoring associated with verification of compliance with the Comprehensive Nuclear-Test-Ban Treaty (CTBT): 131mXe, 133mXe, 133Xe, and 135Xe.
Medical and industrial radioisotopes are fundamental tools used in science, medicine, and industry with an ever expanding usage in medical practice where their availability is vital. Very sensitive environmental radionuclide monitoring networks have been developed for nuclear-security-related monitoring [particularly Comprehensive Test-Ban-Treaty (CTBT) compliance verification] and are now operational.
Summary On July 1-3, 2009, in Strassoldo, Italy, more than 70 professionals representing the medical isotope production and the international monitoring communities from 16 countries came together to discuss the impacts of medical isotope production on the international monitoring system at the Workshop on Signatures of Medical and Industrial Isotope Production (WOSMIP).
