  • 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 ...

  • Biological monitoring and surveillance results of Gulf War I veterans exposed to depleted uranium

    Objective: To relate medical surveillance outcomes to uranium biomonitoring results in a group of depleted uranium (DU)-exposed, Gulf War I veterans. Methods: Thirty-two veterans of Gulf War I who were victims of ‘friendly fire’ involving DU weapons, in whom exposure assessment can accurately be measured, had urine uranium concentrations determined using ICP-MS technology. Clinical laboratory ...

  • Ultrasonic density measurement of uranium loaded organic phase in solvent extraction process

    The application of ultrasound technique in density determination of uranium loaded organic phase in solvent extraction can provide a unique solution for online density monitoring of process streams. Earlier various authors have investigated the density measurement of liquid by single ultrasound frequency. In general standard reference liquid (having low viscosity and density) is used for ...

  • Using k0-UNAA for the determination of depleted uranium in the moss biomonitoring technique

    The use of ammunition containing depleted uranium (DU) in several military actions is of growing health concern to the population related to the risk arising from contamination of the environment with DU penetrators and dust. Environmental monitoring of uranium and its isotopic ratios therefore become important parameters since they allow for source identification. Neutron activation analysis ...

  • Project profile - uranium treatment system village of Marshfield, VT

    Background Following a very successful pilot test, AdEdge Technologies Inc. (AdEdge) was selected in 2007 by the Village of Marshfield, VT and the site’s engineer, Forcier Aldrich & Associates (FA&A), to supply and install a full scale uranium treatment system using its AD92 regenerative Ion Exchange (IX) Technology. Given the high naturally occurring uranium of 76 ug/L ...

  • Can natural variability trigger effects on fish and fish habitat as defined in Environment Canada's metal mining environmental effects monitoring program?

    The Metal Mining Effluent Regulations (MMER) took effect in 2002 and require most metal mining operations in Canada to complete Environmental Effects Monitoring (EEM) programs. An “effect” under the MMER EEM program is considered any positive or negative statistically significant difference in fish population, fish usability, or benthic invertebrate community EEM‐defined endpoints. Two ...

  • Barona Resort & Casino, California - Case Study

    In mid 2007, AdEdge was contacted by Pacific Advance Civil Engineering group (PACE) to assist a Native American Tribe in Southern California near San Diego to provide a packaged treatment system for uranium removal. The Barona Band of Indians owns and operates the water system serving the Barona Resort and Casino. Water from three existing wells combines together with an average uranium ...

  • Elemental composition analysis in lichens transplanted to the western region of Catamarca, Argentina

    Thalli of the lichen Parmotrema austrosinense were collected in their natural non-polluted habitat and transplanted to 18 monitoring sites within an area of the western region of Catamarca province (Argentina) where fruticose lichens are absent. This region is going through a reactivation phase, owing to large-scale mining development and agricultural expansion. The concentrations of 25 elements ...

  • Effects of chronic radon-related external and internal irradiation: assessment of the dose effect curve below 200 mGy

    The long-term effects of professional exposure to radon are well-known. They result from the combined action on the lung epithelia of α-radiation due to radon inhalation and deposition in the lung of its decay products and external γ-radiation from uranium, thorium and their progeny. According to the guidelines applied by the USEPA and recommended by the ICRP, the maximal exposure in ...

  • Cleaner Production In Sensitive Arid Zones: WMC Limited

     WMC Limited (WMC) has progressively introduced process changes at its Olympic Dam mine site and processing plant in the arid north of South Australia to reduce its water consumption per unit of production, and is continuing to investigate further water conservation possibilities. Background WMC is one of Australia's largest mining companies. Its main business ...


  • The effect of quench on Quantitating Alpha Radionuclides by Liquid Scintillation Counting

    Detecting and quantitating alpha emitting radionuclides are routine tasks in nuclear energy and environmental monitoring. For this purpose, liquid scintillation counting (LSC) is an excellent method because alphas are counted with nearly 100% counting efficiency with low backgrounds, even with severe quenching. Quenching agents such as inorganic acids, organic acids, and extractive scintillators ...

  • Dredging at weldon spring super fund project Morrison Knudsen - St. Charles, Missouri, USA

    Remote controlled Dredging proved to be the best method of removing radioactive sludge from settling ponds of a former uranium processing plant near St. Charles, Missouri. Dredging keeps the material wet and out of contact with the atmosphere throughout the removal and treatment process, eliminating the danger of contaminates becoming airborne. The Weldon Spring Site Remedial Action Project ...

  • Aerial Radiation Detection

    In this time of multiple threats to our security: dirty bomb; cyber; shooters in public places; homemade bombs; misinformation; etc. we feel extremely vulnerable; perhaps more vulnerable than ever before. With the advent of Drone technology now available to private citizens, technology previously only held by the military, the opportunity has come to marry Drone Technology with aerial sensors. ...

  • Heavy Metals Water Testing Powered by DNA

    Water pollution is a worldwide problem affecting developing and developed countries alike. Heavy metal contaminants are one prevalent type of water pollutant. They are persistent in the environment once d is charged and removal from source waters is necessary to ensure a clean drinking water supply. The problem of heavy metal pollution arises from several sources. Heavy metals such as uranium can ...

  • Environment and Health

    Public concerns, evidence from research and increasing scientific knowledge are all driving widespread discussions on environment and health problems. The issue of environment and health is characterised by multi-causality with different strengths of association. This means that the links between exposures and their health consequences depend on the environmental pollutants and diseases being ...

  • 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 ...

  • Hydrogen Storage - Solution for an Intermittent Energy Source

    Storing solar energy through hydrogen versus traditional storage solutions Today, energy is either transmitted directly to the consumer through the grid or stored as backup power for future use via batteries, pumping water, etc. When it comes to solar and wind energy, it becomes extraordinarily difficult to take full advantage of the renewable sources using traditional methods of power ...

  • 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 ...
