  • 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, ...

  • Radiation Water Monitor in Real-Time and Continuous at Jefferson NL 2006

    Jefferson National Laboratory is a high tech laboratory located on a beautiful campus in suburban Virginia. Their research is centered on their high-energy electron accelerator. Energies generated are as high as 6 Gev continuous with currents up to 200 micro Amps. Where does the high-energy accelerator beam go after smashing atoms in the experimental sample? It impacts into a tank of purified ...

  • Plant area monitoring at Krško

    Post-Fukushima upgrades at Krško in Slovenia (www.nek.si) are being implemented in accordance with the requirements of the national regulator and the plant owners. The first phase, including a passive containment vent filtering system and hydrogen recombiners, a new emergency diesel generator, and a protected store of mobile emergency equipment, is already completed. The next phase in ...

  • Monitoring landfill gas - Case Study

    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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • The Belgian Nuclear Research Centre and the possibilities for cooperation with China

    This paper gives a short overview of the activities of the Belgian Nuclear Research Centre (SCK?CEN) and the role it can play in the cooperative agreement that was established between the China National Nuclear Corporation (CNNC) and SCK?CEN. Indeed, the current established cooperation on nuclear energy research between China and Belgium should make use of the nuclear research experiences and ...

  • Impacts of aquatic macrophytes configuration modes on water quality

    Constructed wetland technology is regarded as an important ecological restoration technology and used widely in sewage disposal. In order to give them a wider scope of application and to improve their performance in water restoration, the current experiment was designed. Four aquatic macrophytes (dwarf cattail (TM), yellow-flowered iris (WI), water shallot (ST) and watermifoil (MS)) were picked ...
