The distribution of U, Th and 226Ra derived from the phosphate fertilizer industries on an estuarine system in Southwest Spain
TLDR
In this article, an extensive study of the presence of natural radioactivity around a phosphate fertilizer factory complex situated in an estuarine area of southwest Spain was conducted, and it was concluded that the wastes from such industries are the cause of the enhancement of NATR in the immediate environment, and significantly high levels of U- and Th-isotopes and 226Ra were detected in water and sediment samples collected in this area.About:

Natural radioactivity in farm soil and phosphate fertilizer and its environmental implications in Qena governorate, Upper Egypt
TL;DR: Samples of phosphate fertilizers and farm soils, taken to a depth of up to 30 cm in cultivated land, were collected over the Qena governorate, Upper Egypt and activity concentration of background radionuclides such as (226)Ra, (232)Th and (40)K of these samples were determined by gamma-ray spectrometry.

Thorium and uranium uptake by natural zeolitic materials
TL;DR: In this paper, the thorium and uranium uptake from their aqueous solutions by unpretreated and NaCl-pretreated zeolite-bearing volcanoclastic rock samples from Metaxades (Thrace, Greece) has been studied using a batch-type method.
Journal ArticleDOI
Phosphate mineral fertilizers, trace metals and human health
TL;DR: The leachability and dispersion of some of these toxic elements are most pronounced in some types of soils such as andisols as discussed by the authors, which are particularly abundant in these hazardous elements and they contaminate the agricultural soils through the use of fertilizer.

Impact of phosphate industry on the environment: a case study.
I. Othman,M.S. Al-Masri +1 more
TL;DR: The results showed that the distribution and enhancement of natural radionuclides in the surrounding environment in these three locations are mainly due to fallout of phosphate dust generated during loading and processing of phosphate ore, and the extent of contamination was related to climate conditions.

Radioactive impact in sediments from an estuarine system affected by industrial wastes releases
TL;DR: The obtained results indicate that the main pathway of radioactive contamination of the estuary is through the dissolution in its waters of the radionuclides released by the industrial activities and their later fixation on the particulate materials.

Natural radionuclides in the water of Narragansett Bay
TL;DR: The concentrations of radionuclides of the U-Th series (238U,234Th,234U,230Th,226Ra,210Pb,210Po, and232Th,228Ra,228Th) in the water of Narragansett Bay are reported in this paper.

Amazon and Mississippi river concentrations of uranium, thorium, and radium isotopes
TL;DR: In this article, the concentration of uranium and thorium series isotopes was measured in two large samples of river water and associated sediment, and an oceanic residence time for uranium of 4 m.y.

Uranium series disequilibrium in river sediments and waters: the significance of anomalous activity ratios
TL;DR: In this article, the effects of open-system phase transfer on the U series disequilibria observed in the river waters and sediments and investigate the controls exerted on this phase-transfer by the hydrological regime.
Journal ArticleDOI
Radioactivity released from phosphate-containing fertilizers and from gypsum
TL;DR: In this article, potential radiological impacts resulting from direct exposure, surface run-off, inhalation and ingestion of foods grown with fertilizers are discussed, and waste gypsum piles, a byproduct of fertilizer production, are a significant source of radon emissions to air.
