{sup 210}Pb as tracer of environmental processes; El {sup 210}Pb como trazador de procesos ambientales

Abstract

{sup 210}Pb is a radionuclide naturally occurring radioactive belonging to the chain of {sup 238}U. Its half-life is T{sub 1/2} = 22.23 {+-} 0.12 yr. There is some discrepancy in the order of 0.1% of this value and, therefore, not significantly affect the results of the chronology, affected by sources of much greater uncertainty. Assuming that {sup 210}Pb can be detected up to about 5 times its half-life, we can expect that {sup 210}Pb can provide useful information for the last 100 years or so, although this depends on the analytical techniques used and the precision of the assay. {sup 210}Pb plays an important role in the study of the environment as it is present in the atmosphere, lithosphere and hydrosphere. This tracer has been used successfully in the study of biogeochemical processes in the oceans, atmospheric deposition and anthropogenic pollution, sedimentary processes and sediment geochronology.

abstractNote = {{sup 210}Pb is a radionuclide naturally occurring radioactive belonging to the chain of {sup 238}U. Its half-life is T{sub 1/2} = 22.23 {+-} 0.12 yr. There is some discrepancy in the order of 0.1% of this value and, therefore, not significantly affect the results of the chronology, affected by sources of much greater uncertainty. Assuming that {sup 210}Pb can be detected up to about 5 times its half-life, we can expect that {sup 210}Pb can provide useful information for the last 100 years or so, although this depends on the analytical techniques used and the precision of the assay. {sup 210}Pb plays an important role in the study of the environment as it is present in the atmosphere, lithosphere and hydrosphere.

Existen ciertas discrepancias del orden del 0.1% sobre este valor y, por lo tanto, no afectan de forma relevante a los resultados de la cronologia, afectada por fuentes de incertidumbre mucho mayores. Asumiendo que el {sup 210}Pb puede ser detectado hasta unas 5 veces su periodo de semidesintegracion, podemos esperar que el {sup 210}Pb pueda proporcionar informacion util durante los ultimos 100 anos aproximadamente, si bien esto depende de las tecnicas analiticas utilizadas y la precision del ensayo. El {sup 210}Pb juega un papel importante en el estudio del medio ambiente ya que esta presente tanto en la atmosfera, la litosfera y la hidrosfera. Este trazador de procesos ambientales ha sido utilizado con exito en el estudio de procesos biogeoquimicos en los oceanos, deposito atmosferico y contaminacion antropogenica, procesos sedimentarios y geocronologia de sedimentos.}
