radiation waste monitoring Articles

  • Ionising Radiation

    Introduction The energy level of some types of radiation is high enough so that when they interact with matter they cause the formation of electrically charged particles or ion-pairs and break molecular bonds. These so-called ionising radiations are by their nature potentially harmful to life; at high doses they can be lethal and at lower doses can cause genetic damage. Ionising radiation occurs ...

  • Continuous Real Time Water Monitoring for Radiation Safety Terrorist Attack, Improper Disposal of Industrial Waste, Accidental Discharge

    Safe drinking water is essential to life on earth. Unfortunately, this vast infrastructure suffers from critical vulnerability. Keeping America safe with continuous real time water monitoring is a vital goal and is currently being addressed for biological and chemical risks. For monitoring of radionuclides in drinking water as recommended in the Safe Drinking Water Act 8, the Clean Water Act 9, ...

  • FRACKING: Freeing Energy Resources versus Polluting the Earth and Public Health with Radiation and Toxic Chemicals?

    Fracking demands the use of millions of gallons of water, precious drinking water, and sand infused with up to 1,000 different toxic chemicals to fracture the shale rock and release the trapped gas or oil. The wastewater, brine, and sludge are then returned to the surface and in need of disposal. Unfortunately there is not yet a clear and safe method of disposal or storage. Among these chemicals ...

  • Case study - Monitoring landfill gas

    Infrared absorption Infrared absorption is usually the preferred method for measuring methane and carbon dioxide. Most gases absorb radiation in the infrared region. The wavelength of radiation that is absorbed is determined by the natural vibration frequencies of the molecule. These natural frequencies will depend on several factors. Thus different gas molecules have different natural ...

  • Status of black carbon monitoring in ambient air in Europe

    Black carbon (BC) is increasingly discussed in science and environmental policy areas as an example of an air pollutant that affects both human health and contributes to climate change (e.g. WHO, 2012; UNEP/WMO, 2011; Bond et al., 2013; IPCC, 2013). In order to be able to make comparable measurements of BC in ambient air and to relate BC monitoring to health impacts and climate change it is ...

  • Radioactive waste buried beneath Runit Dome on Enewetak Atoll, Marshall Islands

    In the early 1970s after extensive characterisation of fallout the US Pacific Proving Grounds located at Enewetak Atoll began rehabilitation in preparation for the return of indigenous people who were relocated during the Cold War. Cleanup entailed removal and collection of ∼545 GBq of contaminated topsoil, vegetation, and debris (concrete and metal) that was subsequently entombed within an ...

  • Radioactive waste management technologies used in rehabilitation of radioactively contaminated facilities and areas at the RRC 'Kurchatov Institute' site

    Activities on rehabilitation of eleven temporary radwaste repositories are currently underway at the RRC 'Kurchatov Institute'. Technologies used for exploratory drilling of repositories, their radiation survey, cleaning fill-up soil from the repository ceilings and opening the ceilings, RW extraction, sorting and packing in containers are presented. The radiation situation at the repository site ...

  • Radiological safety and environmental monitoring aspects of mining and processing of uranium ore at Jaduguda, India

    Low–grade uranium ore is mined and processed in India since the early 1970s. To adhere to the regulatory compliance monitoring of external gamma level, radon and long–lived alpha activity of ore dust is carried out in uranium mines. Apart from this, surface contamination is also monitored in radiologically important areas of ore processing plant. Exposure of occupational workers is evaluated ...

  • Dye-sensitised photocatalytic degradation of PVC-ZnO composite film

    The hazard of the disposal of waste plastics, such as Polyvinyl Chloride (PVC), has been considered as world-wide environmental problem. In this work, a composite film comprising PVC and ZnO semiconductor has been prepared and characterised. The efficacy of ZnO to degrade the PVC photocatalytically under UV irradiation with and without Eosin Y dye sensitiser has been explored. The process ...
