On the frame of a broad project devoted to the evaluation of the occupational and environmentalradiological impact of several NORM industries located at the South-West Spain, a study determiningthe U-series radionuclides levels in air particulate matter has been accomplished inside a phosphate rockprocessing plant dedicated to phosphoric acid...

Phosphogypsum (PG) is a by-product of the phosphoric acid production process that contains high concentrations of U-series radionuclides. PG piles formed during the last 30 years cover about 1,200 hectares and are located close to the town of Huelva (Spain) on a salt-marsh. The regional government of Andalusia restored the area beginning in...

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...
