Abstract Rare Earth Elements (REE) are becoming increasingly important economically and
highly exploited, thus contributing to REE increases in ecosystems. The ecotoxicological …

Laser-induced breakdown spectroscopy (LIBS) was used to detect rare-earth elements
(REEs)–Ce, La, Nd, Pr, and Sm–in ores. The problems of significant overlap** of REE …

In this study, we utilized a handheld LIBS (laser-induced breakdown spectroscopy) analyzer
(Z-300, SciAps) to quantitatively determine cerium and lanthanum in ores enriched with rare …

Studies regarding background concentrations of rare earth elements (REEs) are scarce and
have mainly focused on a limited number of soil types from the northern hemisphere. The …

A combined use of comparator instrumental neutron activation analysis (INAA) including the
internal standard method and energy-dispersive X-ray fluorescence spectrometry (EDXRF) …

One of the important rare earth deposits is the Dong Pao localized in Lai Chau province,
West-North of Vietnam. Generally, the deposit is composed of two parts, the lower and the …

The largest uranium-phosphate deposit in Brazil also contains considerable levels of rare
earth elements (REEs), which allows for the co-mining of these three ores. The most …

Abstract Pedra Municipality in Pernambuco State (Northeastern Brazil) is known for
encompassing areas with high natural radiation from 238 U sources, contaminating soil …

Рассмотрено совместное применение компараторного инструментального нейтронно-
активационного анализа (ИНАА) с использованием способа внутреннего стандарта и …

The continuous use of fertilizers can increase the radionuclides levels in soils, and their
accumulation and concentration are related to their characteristics and the various …
