Abstract Since more than 100 years, the adsorption of radioactive noble gas radon ( 222 Rn) is performed on activated charcoal at cryogenic temperatures. There little—if any—progress in field ambient conditions to facilitate development simple and compact systems. We report here truly remarkable property synthetic silver-exchanged zeolites Ag-ETS-10 Ag-ZSM-5 strongly adsorb room temperature. Rn breakthrough experiments nitrogen carrier have shown that these materials exhibit coefficients...
Worldwide monitoring of radionuclides is an essential part the verification system Comprehensive Nuclear-Test-Ban Treaty (CTBT) as it can provide a direct evidence nuclear nature explosion. In case underground testing, radioactive noble gases, specifically radioxenon, have highest probability to escape atmosphere. The detection capability CTBT gas network, which being built, weakened due presence worldwide civilian radioxenon background. Improving understanding and knowledge sources their...
In April 2020, several wildfires took place in and around the Chernobyl exclusion zone. These fires reintroduced radioactive particles deposited during 1986 disaster into atmosphere, causing concern about a possible radiation hazard. Several countries stations of International Monitoring System measured increased Cs137 levels. This study presents analyses made by RIVM SCK CEN/RMI 2020 wildfires. Furthermore, more in-depth research was performed after A statistical analysis detections is...
Efficient porous adsorbents are crucial for the mitigation of radioxenon emissions from nuclear installations. They also important production Xe and detection clandestine weapon tests. Silver-exchanged zeolites or zeolite-like frameworks, specifically Ag-ZSM-5 Ag-ETS-10, promising candidates these applications. However, their radiation resistance has not yet been sufficiently investigated further research on durability against thermal regeneration cycles would support use such The...
More efficient adsorbents for Xe collection and separation from air could provide new alternatives cost-efficient production of stable as well trace measurements atmospheric radioxenon. Silver-exchanged Zeolites (AgZs) have been reported to be more than Activated Carbon (AC) in collecting at low pressures room temperature but never air. Metal-Organic Frameworks (MOFs) high Xe/Kr selectivities Kr enriched gas streams either. Two AgZs (Ag-ETS-10 Ag-ZSM-5), two MOFs (HKUST-1 Ni-DOBDC) one AC...
