A big fertilizer industrial complex and a vast extension of phosphogypsum piles (12 km2), sited in the estuary formed by the Odiel and Tinto river mouths (southwest of Spain), are producing an unambiguous radioactive impact in their surrounding aquatic environment through radionuclides from the U-series. The levels and distribution of...

El objetivo de esta investigación ha sido analizar la valorización de un residuo generado en el proceso de pro-ducción de dióxido de titanio (vía sulfato), denominado yeso rojo, en la producción de cementos. Dicho residuo está compuesto fundamentalmente por sulfato de calcio dihidratado e hidróxidos de hierro. Para ello, ha sido necesaria la...

Liquid scintillation counting (LSC) is an easy and straightforward technique, and combined with its low limit of detection, makes it a powerful tool for both routine and low level measurements that can be applied to 210Pb low level counting in environmental samples. 210Pb can be easily measured following a sulphate co-precipitation method; the...

In this paper a simple, rapid and general method for g-ray efficiency calibration of Ge detectors for environmental samples is presented. This method is based on the use of an active natural solid sample with several g-emissions (in our case, 226Ra) as the calibrating matrix for determining the full energy peak efficiency (FEPE) ec vs...
