In various methods to determine alpha-emitting radionuclides in matrices, alpha-particle spectrometry with alpha-emitting sources prepared by the electrodeposition has been widely used. Although there are several good review papers on alphaparticle spectrometry and preparation of electrodeposited alpha-emitting sources, the mechanism of analysis procedure and characterizations of alpha-emitting sources have not been reported well. These untouched subjects by other review papers are very significant to improve the analysis procedure. This review focuses on the mechanism of the electrodeposition of alpha-emitting radionuclides on the stainless steel disc, factors for the preparation of electrodeposited alpha-emitting layers, and various characterization methods.

“…Httfa is a potant chelating agent and widely used in extraction and analysis of many transition and rare earth metals. Determination and extraction of cadmium, zinc, manganese, plutonium and gallium have been done in solvent even at very low concentration in the form of their metal complexes with Httfa ligand by synergistic extraction and back‐extraction methods . Its derivative is useful in extraction and separation of uranium and polychlorinated biphenyls (PCBs) from contaminated soil samples using a sequential supercritical CO 2 extraction method .…”

Mn(II), Co(III), Ni(II), Cd(II) and Cu(II) Complexes of 2‐Thenoyltrifluoroacetone: Syntheses, Structures, Photoluminescence, Thermal, Electrochemical and Antitumor Studies on Dalton's Lymphoma Cells

Five complexes [Mn(ttfa)2(py)2] (1), [Co(ttfa)3] (2), [Ni(ttfa)2(en)] (3), [Cd(ttfa)2(bpy)] (4), and [Cu(ttfa)2(py)] (5) {where Httfa=2‐thenoyltrifluoroacetone} have been synthesized and characterized by elemental analyses, IR, UV‐Vis and single crystal X‐ray diffraction data. Both oxygen atoms of ttfa chelate with the metal ions forming six‐membered C3O2M chelate rings in the complexes. In complexes 1–4 the metal ion adopts a distorted octahedral geometry while the complex 5 is distorted square pyramidal. In the solid state, complexes are stabilized by various types of inter‐intramolecular interactions. Upon excitation at about 29500 cm−1, complexes 1, 2, 3 and 5 exhibit blue emissions while the complex 4 emits violet colour. Electrochemical studies of Httfa and complexes show irreversible redox behavior. Thermal degradation of the complexes as analyzed by TG‐DTA suggests the formation of their respective metal oxides as final thermally stable chemical entities. Httfa, complex 1 and 5 are studied for cytotoxicity on Dalton's lymphoma cells using MTT assay, apoptotic analysis and DNA fragmentation assay which reveals their order of activity as complex 5 > complex 1 > Httfa.
