Organic pollutants comprise a potential group of chemicals which can be dreadfully hazardous to human health. As they persist in the environment, they are capable of long range transportation, bioaccumulation in human and animal tissue and biomagnifications in food chain. Phenolic compounds are hazardous pollutants that are toxic at relatively low concentration. The use of microbial catalysts i...

Thermal history and apatite fission-track ages were determined for the Kaleybar, Razgah and Bozqush alkaline intrusions which display Eocene-Oligocene stratigraphic age. These subduction-related intrusions are located in the Alborz-Azarbaijan magmatic belt which is characterized by a Paleogene magmatic flare-up associated with extensional/transtensional tectonism. The mean of Uranium content an...

For more than 20 years, the OECD Nuclear Energy Agency (NEA) has been conducting international studies related to the partitioning and transmutation (P&T) of nuclear waste, including physics, chemistry and material issues, as well as fuel cycle and radioactive waste management strategies. The information exchange meetings on actinide and fission product partitioning and transmutation, organised...

Technetium is an element that is artificially produced and all its isotopes are radioactive. Several investigations have been performed on the subject of the production of Tc radioisotopes using cyclotrons. Among these radioisotopes, 99mTc with a half-life of 6.02 h and gamma-ray spectrum with an energy peak at 140.5 keV has a vast application in nuclear medicine. More than 85% of administered ...
