The methods are based on total decomposition of the solid materials by the use of closed vessels microwave acid digestion systems and preconcentration of uranium from the liquid samples by iron hydroxide co-precipitation (after heating in case of underground or carbonated waters). The separation of uranium from interfering radionuclides (thorium, polonium, etc.) and stable matrix elements...

In the environmental studies the determination of low concentrations has always been a key issue and therefore, the concentration step is usually a crucial part of the sample processing. For the extraction of uranium, sorption materials based on titanium dioxides have been proposed and studied for years with promising results. Implementing titanium dioxide materials as a sorption material and...

The ability to examine elemental and isotopic ratios of fuels, waste forms, and other solids by direct analysis using laser ablation techniques can greatly reduce analysis costs and time. This is particularly true for actinide elements, as they contain useful information of the fuel cycle and nuclear forensics. Current methods to evaluate the composition of used fuel include a lengthy...

Lead-210 is a natural radioactive isotope that is commonly used in erosion and sedimentation studies. It may also bioaccumulate through the foodchain, which has implications for human ingestion dose assessment and assessment of radiation doses to biota. While analysis via gamma spectrometry is the method of choice for most sediments and soils, the ability to measure low levels of lead-210 is...

Yerba mate, Ilex Paraguayensis, is a plant of paraguayan origin used in infusions by the ancient inhabitants of Paraguay as a “reviver”/energy beverage which consumption is lasting up today; furthermore, it is extended almost worldwide. In regard to its mineral content very few studies are known; moreover, none has been published related to the occurrence of REE (rare earth) and other...

The health and performance of grazing ruminants are dependent on the availability of essential mineral elements from pastures but the pastures often fail to supply all needed mineral elements in the quantity adequate for livestock grazing.
Species-rich grasslands with Nardus stricta are one of the important environments for animal production not only in Romania but also in other European...
