The recycling of inorganic wastes generated by different industrial processes is a research field of high interest because the minimization of waste disposal, avoiding its potential release into the environment, can generate environmental and economical benefits for these industries and the general ...

The present study was focused to characterize the raw materials, wastes and several co-products from titanium dioxide industry, in particular their elemental composition (major, minor and trace elements), mineralogy, and radioactive contents, with the objective to apply this knowledge to ...

El presente trabajo tiene como objetivo la caracterización físico-química y radiactiva, de las materias primas (ilmenita y slag), residuo (yeso rojo) y co-productos (caparrosa y monohidrato), procedentes de la industria de producción de dióxido de titanio. Para ello, se analizó su composición elemental (componentes mayoritarios y elementos...

Knowledge of accurate radio isotopic signatures is very necessary in assessing any potential radiological hazards and risks to members of the public and workers from exposure to NORM contaminated scales. In this work scales from crude oil production activities from Ghana have been assessed using ...

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...

The production of phosphate fertilizers usually uses as raw material sedimentary phosphate rock, which contains enhanced concentrations from U‐series radionuclides about 10–100 times higher than unperturbed soils. This fact implies the need for evaluating the radiologi‐cal implications of this activity. In our case, the study has been...

The estuary formed by the confluence of Tinto and Odiel river-mouths is located in the South of Spain, close to Huelva town. This estuary has been deeply studied through the years because it has a double particularity. On one hand, since the beginning of the 1960s, the estuary has been affected by ...

Peat lands are archives of past diversity, climate, and other environmental conditions. The redistribution of radionuclides in a peat bog after a fire consists of change in vertical distribution and releases/losses to the atmosphere through evaporation and resuspension. The study of different...

The Upper Moulouya Lead district is a region of Morocco affected by the presence of mining deposits, pit lakes and other mining wastes, due to the former mining activities developed in the 20th century. The Middle Moulouya is a region not affected by human activities and is studied for a better comprehension of results obtained...

The main aim of this work was to determine the levels of multiple natural radionuclides in an aquatic system(Moulouya river, Morocco) impacted by multiple abandoned Zinc and Lead mines.238U,234U,232Th,230Th and210Po were determined by alpha-particle spectrometry in water and sediment samples collected along the riverand in samples from three...
