Thematic Session 1: Studies of Climate Change
- Iolanda Osvath (IAEA)
ABSTRACT
Alpine glaciers are among the most sensible indicators of climate change. Physical changes in glaciers are in fact a direct and visible evidence of a change in temperature and precipitation regime. Glaciers are also natural archives, registering during their lifetime information about past temperature, precipitations, atmospheric composition. Ice cores give the possibility to access...
Surface glacier ice maintains historical records of global fallout radionuclides from the atmospheric nuclear weapon testing (NWT) period. These radionuclides have found important applications for developing and/or validating ice core chronologies and ice flow models. Among the artificial radionuclides, plutonium-239 (239Pu, half-life: 24 100 yr), plutonium-240 (240Pu, half-life: 6 561 yr),...
Accurate knowledge of the low-level atmospheric radon activity concentration and radon fluxes are key parameters in the evolution of climate observations as well as radiation protection.
The need for traceable low-level atmospheric radon concentration measurement of two communities – climate observation and radiation protection – are joined under the EMPIR project traceRadon$^1$. This...
ABSTRACT
Atmospheric measurements of radon activity concentration seem to be very useful for the assessment and improvement of atmospheric transport models (ATM). Radon can be used as a tracer to evaluate dispersal models important for identifying successful greenhouse gas (GHG) mitigation strategies. For this purpose, the “traceRadon” (Radon metrology for use in climate change observation...
