Radioactive factors in water pollution
The Canadian Journal of Chemical Engineering, 1962AbstractThis paper is primarily concerned with the introduction of radionuclides into bodies of water as a result of nuclear reactor operations. When radioactive materials are dispersed in surface waters, several factors such as water usage and biological concentration in human food chains must be considered.

Dispersion of radioactive pollution in surface water
Ecological Modelling, 1984Abstract A mathematical description of the dispersion of radioactive pollution in surface water is presented based on a discussion of the phenomena, which influence it. A differential equation in the general form is obtained and simplified to give the most convenient solution for the investigation of radioactive doses during normal operation of the ...

Research on underground water pollution caused by geological fault through radioactive stratum
Journal of Radioanalytical and Nuclear Chemistry, 2012The earthquakes cause appearance of new geological fault and dislocation of rock stratum; the original permeable rock breaks, then the fault can conduct water under the effect of pressure; the stratum with radionuclide is dislocated and connected to the water-conducting fault under the effect of the fault.

Green Sorbents for Radioactive Pollutants Removal from Natural Water
2018Natural and anthropogenic radionuclides are a major pollution of natural waters in some locations. Effective, appropriate and eco-friendly technologies are required to mitigate this problem. Natural materials can be used, which may help in rehabilitation and reduction in migration of radionuclides execution green technological concept.

A Quick Radioactivity Measuring Instrument for Emergent Nuclear Pollution Detection in Body Of Water
2017 IEEE Nuclear Science Symposium and Medical Imaging Conference (NSS/MIC), 2017This manuscript presents a portable Liquid Scintillation (LS) coincidence instrument for quick radioactivity measurement in water, which is based on high speed Analog to Digital Converter (ADC) direct sampling. To meet the requirement of emergent water nuclear accident onsite detection, the instrument is designed to be portable and quick to detect. The

Hydrotalcite (HT)-based materials are usually applied to capture anionic pollutants in aqueous solutions. Generally considered anion exchangers, their ability to capture radioactive cations is rarely exploited. In the present work, we explored the ability of pristine and calcined HT getters to effectively capture radioactive cations (Sr(2+) and Ba(2+))

Waters polluted with toxic heavy metals, radioactive elements, arsenic and sulphates were efficiently treated by means of a laboratory-scale passive system consisting of an anaerobic cell and a constructed wetland. These waters were polluted in a stream receiving leachates from an operating copper tailings dam and other effluents from man-induced ...

A urea-functionalized ordered mesoporous polymeric nanoparticle for removing the perrhenate anion ReO4- as the surrogate of the particularly intractable anion radioactive pollutant TcO4- was demonstrated in the present study. This nanomaterial (denoted as urea-MPN) was produced for the first time by a surfactant-directed urea-phenol-formaldehyde resol ...

Journal of Environmental Radioactivity, 2014
The studies were conducted in the territory contaminated by (90)Sr with groundwater inflow as a result of leakage from the near-surface trench-type radioactive waste storage. The vertical soil (90)Sr distribution up to the depth of 2-3 m is analyzed.
