La Segunda Guerra Mundial finalizó prácticamente con el lanzamiento de dos bombas nucleares a las ciudades japonesas de Hiroshima y Nagasaki. Inmediatamente después comenzó una enorme escalada en la realización de pruebas nucleares atmosféricas por las grandes potencias, cada vez de mayor energía, con la consecuente liberación de radiactividad...

La determinación de los valores de una fracción del radionidido natural 210Pb a diversas profundidades del sedimento permiten un fechado en el rango temporal de los últimos 150 años. Por ello se han estudiado en esta tesis todas las bases experimentales y teóricas necesarias para el fechado de los sedimentos aplicando este método. Ello...

The Constant Flux: Constant Sedimentation (CF:CS) and Constant Rate of Supply (CRS) of unsupported⧸ excess 210Pb models have been applied to a 210Pb data set providing of eighteen sediments profiles sampled at four riverine systems occurring in Brazil, South America: Corumbataí River basin (S1¼Site 1, São Paulo State), Atibaia River basin...

Detailed mappings of the external exposures which can be received by the workers in two NORM industrial factories located at the South-West of Spain have been performed: one devoted to the production of phosphoric acid, and the other devoted to the production of titanium dioxide pigments. In most ...

In this paper a general method for y-ray efficiency calibration is presented. The method takes into account the differences of densities and counting geometry between the real sample and the calibration sample. It is based on the y-transmission method and gives the correction factorf as a function of Ey, the density and counting geometry....

In this editorial a summary of the main contributions and outcomes of the conference celebrated in Seville about Radioecological Concentration processes during six intense sessions is given. It was quite remarkable in addition to the good quality of the communications presented, the active participation of the delegates and the...

El complejo químico de Huelva alberga el mayor conjunto de producción de ácido fosfóricode Europa. La producción de este material, del que se derivan fertilizantes y otros productosde amplio uso, deja como residuo unos compuestos denominados fosfoyesos, que contienenradiactividad de origen natural, de los cuales se han acumulado ya más de 80...

This model is a improved version of a previously published Two-Scales model 1111 and includes the transport of particles in three spatial scales: small (kilometres), medium (decades of km), and large (hundreds of km). A 3-D dispersion model has been developed to analyse and simulate the dispersion of nuclear contaminants in marine ecosystems....

By analysing the 239+240Pu and 238Pu content in a total of 32 sediment gravity cores, it has been possible to obtain quite rich information about the accumulation pattern of these radioactive pollutants on the basin of a small lake located in southwest Sweden. In fact, it has been observedthat the traditional lacustrine models reflecting as...

A 3-D dispersion model has been developed to simulate the dispersion of nuclear contaminants in marine ecosystems. This model is characterized by presenting high spatial resolution, by taking into account the possible sedimentation of a fraction of the contaminants, and by formulating the diffusion processes using an original approach. The...

Industrial activities associated with metal mining, extraction and processing of oil and gas, power generation using fossil fuels, among others, may concentrate natural radionuclides in various products, by-products and wastes. Radiological implications of naturally occurring radioactive materials (NORM) generated by human activities need to be...
