Immuno-labelled techniques (ILTs) depend on linking of a specific antibody to a labelling material. The so-produced conjugate is utilized to detect or assay a specific reactant against which the antibody, in the conjugate, is directed. Many labelling materials have been conjugated to specific antibodies. The most commonly used labels included enzymes, avidin-biotin, radioactive materials, fluor...

The present study was focused to characterize the raw materials, wastes and several co-products from titanium dioxide industry, in particular their elemental composition (major, minor and trace elements), mineralogy, and radioactive contents, with the objective to apply this knowledge to valorize these materials in fields such as construction, civil engineering, fertilizers manufacturing, etc.

Accidental or intentional release of radioactive materials into the living or working environment may cause radioactive contamination. In nuclear medicine departments, radioactive contamination is usually due to radionuclides which emit high energy gamma photons and particles. These radionuclides have a broad range of energies and penetration capabilities. Rapid detection of radioactive contami...

The liquid wastes produced during the processing of radioactive materials at the Savannah River Site were initially stored in large underground tanks constructed of carbon steel. These liquid wastes were generated from the Purex process (for producing plutonium) and the HM process (for producing tritium). The liquid wastes were designated as high-level wastes and lowlevel wastes. As the product...

Experts in the US Department of Homeland Security have determined that a possible threat exists for the detonation of Radiological Dispersion Device (RDD) and/or an Improvised Nuclear Device (IND) on US soil. Various US government agencies are currently procuring radiation monitoring systems to attempt to guard our homeland at locations such as border crossings, seaports, airports and post offi...

Iodine radioisotopes are released into the environment by the nuclear industry and medical research institutions using radioactive materials. The (129)I(-) anion is one of the more mobile radioactive species due to a long half-life, and it is a great challenge to design long-term management solutions for such radioactive waste. In this study, a new adsorbent structure with the potential to effi...

It is now well-known that the size, shape, and composition of nanomaterials can dramatically affect their physical and chemical properties, and that technologies based on nanoscale materials have the potential to revolutionize fields ranging from catalysis to medicine. Among these materials, anisotropic particles are particularly interesting because the decreased symmetry of such particles ofte...

Aqueous dissolution of silicate glasses and minerals plays a critical role in global biogeochemical cycles and climate evolution. The reactivity of these materials is also important to numerous engineering applications including nuclear waste disposal. The dissolution process has long been considered to be controlled by a leached surface layer in which cations in the silicate framework are grad...

Transfer of radioactive materials to fixed cells from an overlying layer of living cells has been examined to determine whether fixed cells can act as acceptors of glycosyltransferases of living cells. After the incubation of living cells were removed by EDTA treatment, and the radioactivity associated with the fixed cells was determined. Lipids, proteins and carbohydrates were found to be tran...
