Abstract The handling and storage of the spent fuel from current nuclear power reactors is one major ecological challenges in front energy industry, due to its long period high radiotoxicity. It mainly caused by long-lived minor actinides generated fuel. Therefore profound study possibilities for shortening terms fuels some radioactive waste through currently available technologies necessary. p...

Abstract BACKGROUND CNS injury following brain-directed radiotherapy (RT) is common and may mimic disease progression. Dosimetric advantages of protons (PRT) over photons (XRT) minimize radiation to healthy brain, potentially limiting radiotoxic sequelae. We characterized radiotoxicity i.e., radiation-induced leukoencephalopathy (RIL), brain tissue necrosis (TN), cerebral microbleeds (CMB), dur...

Selective extraction of minor actinides from lanthanides is a critical step in the reduction of radiotoxicity of spent nuclear fuels. However, the design of suitable ligands for separating chemically similar 4f- and 5f-block trivalent metal ions poses a significant challenge. First-principles calculations should play an important role in the design of new separation agents, but their ability to...

Microbial processes can affect the environmental behavior of redox sensitive radionuclides, and understanding these reactions is essential for the safe management of radioactive wastes. Neptunium, an alpha-emitting transuranic element, is of particular importance because of its long half-life, high radiotoxicity, and relatively high solubility as Np(V)O(2)(+) under oxic conditions. Here, we des...

Auger electron emitting radionuclides in cancer therapy offer the opportunity to deliver a high radiation dose to the tumor cells with high radiotoxicity while minimizing toxicity to normal tissue. We have in this study identified the Auger emitter Sb119 as a potent nuclide for targeted radionuclide therapy based on theoretical dosimetry calculations at a subcellular scale. From these calculati...

Radioactivity in nuclear power effluents is negligible compared to that in retained wastes to be disposed of as solids. Two basic waste categories are those for which shallow disposal is accepted and those for which more extreme isolation is desired. The latter includes "high level" wastes and others contaminated with radionuclides with the unusual combined properties of long radioactive half-l...

Ionizing radiations are used regulary to treat various tumors since the discovery of X-rays by Wilhelm Conrad Röntgen in the year 1895 and approximately 40% of patients are cured by radiotherapy and 50% of the patients receive radiotherapy during their disease [1,2]. It is used to treat tumors or as an adjuvant or neoadjuvant therapy and in several instances it is the only modality to treat tum...
