Medical wastes include all infectious waste, hazardous (including low-level radioactive) wastes, and any other wastes that are generated from all types of health care institutions, including hospitals, clinics, doctor (including dental and veterinary) offices, and medical laboratories (42). 1 The main focus of concern has been on the portion of medical wastes that are defined as infectious, and...

Nuclear hazards, linked to both U.S. weapons programs and civilian nuclear power, pose substantial environment justice issues. Nuclear power plant (NPP) reactors produce low-level ionizing radiation, high level nuclear waste, and are subject to catastrophic contamination events. Justice concerns include plant locations and the large potentially exposed populations, as well as issues in siting, ...

It is of great importance to safely dispose nuclear wastes with the development industries. Past approaches this problem have included immobilizing radioactive cesium in Portland cement-based matrices; however, leaching rates are relatively high, especially as temperature increases. This paper explores a high-efficiency and cost-effective approach for encapsulating using sulfoaluminate cement (...

Numerous low-level and intermediate-level radioactive wastes are generated from the decommissioning processes of nuclear power plants; these immobilized to prevent release radionuclides under disposal conditions. In this study, we investigated leaching behavior Cs, Sr, Co, Eu, which common in wastes. Ordinary Portland cement (OPC) was used as an immobilization agent. During test, nuclides occur...

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...

Construction and Demolition (C&D) wastes contribute the highest percentage of wastes worldwide (75%). Furthermore, ceramic materials contribute the highest percentage of wastes within the C&D wastes (54%). The current option for disposal of ceramic wastes is landfill. This is due to unavailability of standards, avoidance of risk, lack of knowledge and experience in using ceramic wastes in const...

Currently, much of our biodegradable wastes such as kitchen wastes, agricultural wastes & animal wastes are used to produce Biogas, a powerful greenhouse gas. Anaerobic digestion (AD) is a treatment that composts these wastes in the absence of oxygen, producing a biogas that can be used to generate Heat & Power. Producing renewable energy from our biodegradable wastes helps to tackle the energy...

by Alexandra f semi-closed tideless basin bordering six Bologa countries, the Black Sea is considered a "unicum hydrobiologicum" because of its physical, chemical, and biological peculiarities. Unlike any other sea, the Black Sea is permanently deficient in oxygen, or anoxic, below a depth of 150-200 meters. The Sea's radioactivity levels have been the subject of rigorous research in the ripari...

In this workN2,N6-di(thiazol-2-yl)pyridine-2,6-dicarboxamide (DPD), was synthesized via reaction of 2-aminothiazole and 2,6- pyridinedicarboxylic acid in n-methylpyrrolidine. The obtained (DPD) was characterized with nuclear magnetic resonance spectroscopy (NMR), Fourier transform infrared (FT-IR) spectroscopy, and elemental analysis. Finally, a novel magnetic nanoadsorbent was synthesized by m...
