A search for the seasonal variability on the depositional fluxes of 7Be and 210Pb
Investigations of the atmospheric fallout of 7Be and 210pb in many places around the globe indicate that there are seasonal variations on the alepositional fluxes of these nuclides: high in winter in a few places, while in most places the high occurs in spring. However, these earlier studies did not address quantitatively the corresponding seasonal variations of the amount of precipitation duri...
متن کاملThe Influence of Topography and Vegetation
Naturally occurring radioactive isotopes of 210Pb and 7Be in the atmosphere, plant material and soil have been used to investigate the transport and removal of atmospheric aerosols from the atmosphere by precipitation and turbulent deposition to natural surfaces. Concentrations of 210Pb and 7Be contained in aerosols in surface air were measured using a high volume sampler at the King’s Building...
متن کاملSeasonal variability in 7Be depositional fluxes at Granada, Spain.
Measurement of 7Be depositional fluxes at Granada, Spain (37 degrees 10'50''N-3 degrees 35'44''W, altitude 670 m) in the period 1995 through 1998 indicates substantial variations between the four seasons and also between corresponding seasons in different years, ranging from 23.6 to 242 Bq m(-2) per season. A strongly positive correlation with precipitation is shown, which explains about 70% of...
