Abstract: | In order to assess the extent of the elimination of humidity and the presence of pine trees on the elemental composition of
airborne dust, the concentration of 21 elements were measured in airborne dust collected with a high-volume sampler at JAERI
by instrumental neutron activation analysis (INAA). It was found that the concentration of soil-origin elements, such as Al,
Sc and Th, decreased as the humidity increased, and the Cl/Na ratio of sea salt constituent in the dust samples increased
with the decrease of humidity after the felling of the trees. |
