Advancement of radioactive material removal system by silver zeolite (Quantitative evaluation of noble gas adsorption characteristics by XeA and construction of noble gas adsorption system)

open access: yesNihon Kikai Gakkai ronbunshu, 2022
In nuclear power plants, measures against radioactive noble gases are required. Until now, special activated carbon that easily adsorbs noble gases has been used in some nuclear facilities. However, activated carbon has a small adsorption capacity and is

Noble Gas Mass Spectrometry in Earth and Planetary Sciences

open access: yesCHIMIA, 2022
: Noble gases are very rare elements in most relevant samples in geochemistry and cosmochemistry. Noble gases may perhaps also look rather boring to chemists, as they do not form any stable compounds.

Determination of natural in vivo noble-gas concentrations in human blood. [PDF]

open access: yesPLoS ONE, 2014
Although the naturally occurring atmospheric noble gases He, Ne, Ar, Kr, and Xe possess great potential as tracers for studying gas exchange in living beings, no direct analytical technique exists for simultaneously determining the absolute ...
