The determination of 90Sr through the Cerenkov radiation emitted by its descendant 90Y is a well-known method and firmly established in literature. Nevertheless, in order to obtain an accurate result based on a Cerenkov measurement, the experimental work must be extremely rigorous because the efficiency of Cerenkov counting is especially sensitive to the(More)
INTRODUCTION Hematopoietic stem cell transplantation, which requires accurate enumeration of stem cells, is routinely used in clinical settings. Flow cytometry provides a qualitative and quantitative assessment of CD34⁺ cells. Precision, linearity, and stability of the novel BD™ Stem Cell Enumeration (SCE) Kit were evaluated on two flow cytometry platforms(More)
After the recent closure of certain phosphoric acid plants located in the South-West of Spain, it has been decided to restore a big extension (more than six hundred hectares) of salt-marshes, where some million tonnes of phosphogypsum (PG), the main by-product generated by these plants, had been disposed of. This PG is characterized by its content of high(More)
The Huelva Estuary in Huelva, Spain, has been one of the most studied environmental compartments in the past years from the point of view of naturally occurring radioactive material (NORM) releases. It has been historically affected by waste releases, enriched in radionuclides from the U-decay series, from factories located in the area devoted to the(More)
In order to fill a gap in the open literature, occupational exposures and activity concentrations have been assessed in two NORM industrial plants, located in the south-west of Spain, devoted to the production of mono-ammonium phosphate (MAP) and di-ammonium phosphate (DAP) fertilisers. The annual effective doses received by the workers from these plants(More)
The thermoconvective flow induced in oil samples and oil-in-water emulsions by irradiation with a laser beam is studied experimentally. The samples are irradiated by He-Ne and CO2 lasers at different power levels. Time-resolved records of temperature and surface waves that propagate in a liquid surface are presented. In laser-heated emulsions the(More)
