Two novel maltol-based ionic liquids, namely [A336][Mal] and [C101][Mal], were synthesized as potential extracting agents for radionuclides from water. These two room temperature task-specific ionic liquids could be easily prepared by anion metathesis starting from commercially available materials. The isolated compounds were characterized by standard analytical methods. Their application as ex...

There are many regulations related to the radiological control of NORMs (Naturally Occurring Radioactive Materials) in activities such as mining, industry, etc. Consequently, it is necessary apply fast and accurate methods measure activity concentrations long-lived natural radionuclides (e.g., 238U, 234,232,230,228Th, 228,226Ra, 210Pb, 210Po, 40K) samples characterized by a wide variety composi...

Phosphogypsum (PG) is disposed worldwide in large stacks usually placed coastal zones, as the case of Huelva (SW Spain), where around 100 Mt PG are stored on salt marshes Tinto River estuary covering a surface about 1000 ha. This management generates weathering PG, and due to its high acidity (pH ≈ 2) pollutant load can provoke significant emissions into their surroundings. In this work were ev...

We have performed shell-model calculations for the N = 126 isotones 210Po, 211At, and 212Rn using a realistic effective interaction derived from the Bonn A nucleon-nucleon potential by means of a G-matrix folded-diagram method. The calculated binding energies, energy spectra and electromagnetic properties show remarkably good agreement with the experimental data. The results of this paper compl...

The mean annual effective dose from natural radionuclides for users of drilled wells was estimated to be 0.41 mSv, for users of wells dug in the ground 0.05 mSv and for people using water from waterworks 0.02 mSv. The highest effective dose from drinking water was caused by 222Rn (Fig. 2) constituting 75% and 60% of the total effective dose caused by all natural radionuclides for drilled-well u...

An assessment has been made of the association of (239+240)Pu, 241Am and 210Po (in secular equilibrium with 210Pb) with iron minerals using a magnetic extraction technique. Grab samples of beach sand from the Cumbrian (UK) coastline were subjected to successive extractions with an approximately 0.1 T ferrite magnet and an approximately 0.3 T rare-earth magnet procedure to separate magnetic iron...
