  • Radiation Monitors and Meters

    Light Description and Applications The light meter is a portable unit designed to measure visible, UV, and near-UV light in the workplace. (The CTC has a UV light meter available through its loan program, ALEP.) The light meter is capable of reading any optical unit of energy or power level if the appropriate detector has been calibrated with the meter. The spectral range of the instrument is ...

  • Non-Ionising Radiation

    Pressures on the environment may occur through chemical, physical and biological agents. The subject of this study is physical agents, where physical fields are examined. Physical fields are part of the natural environment. Depending upon their properties and the surrounding conditions, physical fields are transmitted through the spaces in which we live, potentially affecting human health and ...

  • Physical dosimetry system in radiation accidents

    We experience various types of radiation accidents. When a radiation accident happens, one of the important aspects that we have to consider is the radiation dose to the victims of the accident. To judge the health effects due to radiation exposure, it is necessary to make a dose assessment. There is a variety of dose assessment methods, of two types: biological dosimetry and physical dosimetry. ...

  • 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 ...

  • Wastewater Plant Relies on Thermal Flow Meter for Co-Gen Power Gas Blending Process

    The Rahway Valley Sewerage Authority (RVSA), which operates a large wastewater treatment plant in New Jersey, embarked on a green co-generation waste-to-energy project to power a portion of its operations. The plant performs primary, secondary, tertiary and sludge treatment processes in serving over 250,000 residential customers and 3000 industrial and commercial customers in a 40-plus square ...

  • The investigation and measurement of the radon gas working level inside buildings in Rafsanjan

    Radon gas and its daughters are radioactive and radiate alpha particles with high energy. These particles can cause DNA damage, which may or may not be properly repaired. Also, if these particles get into the lungs for a long period of time, they may damage the lungs' inner tissue. This is one of the most important causes of lung cancer after smoking. This paper presents a report on the ...

  • Plutonium decontamination using CBI DeconGel 1101 in highly contaminated and unique areas at LLNL

    A highly contaminated glove-box at LLNL containing plutonium was decontaminated using a strippable decontamination gel. 6 x 12 inch quadrants were mapped out on each of the surfaces. The gel was applied to various surfaces inside the glove-box and was allowed to cure. The radioactivity in each quadrant was measured using a LLNL Blue Alpha meter with a 1.5 inch standoff distance. The results ...

  • A simple numerical method for snowmelt simulation based on the equation of heat energy

    This paper presents one-dimensional numerical model for snowmelt/accumulation simulations, based on the equation of heat energy. It is assumed that the snow column is homogeneous at the current time step; however, its characteristics such as snow density and thermal conductivity are treated as functions of time. The equation of heat energy for snow column is solved using the implicit finite ...

  • Enhancement of absolute neutron dosimetry by activation technique

    In this work, an activation technique was used for absolute neutron dosimetry. Induced gamma within two activation foils (115In and 197Au) was detected by (5 × 5) sodium iodide (NaI) crystal. Thermal neutron irradiation was performed using the thermal neutron irradiation facility at the National Institute for Standards (NIS). Two gamma ...

  • A Regulatory Perspective on Maintenance of Disinfection Systems

    ABSTRACTThe Clean Water Act contains requirements to set water quality standards for all contaminants, including bacterial contaminants, in surface waters. Wastewater treatment cannot be expected to remove all of the bacterial contaminants, and as a result, many organisms remain in the waste stream. Therefore, disinfection of treated wastewaters is designed to reduce bacterial numbers to a safe ...

  • Harnessing the Sun`s Energy for Water and Space Heating

    The pace of solar energy development is accelerating as the installation of rooftop solar water heaters takes off. Unlike solar photovoltaic (PV) panels that convert solar radiation into electricity, these "solar thermal collectors" use the sun's energy to heat water, space, or both. China had an estimated 168 million square meters (1.8 billion square feet) of rooftop solar thermal collectors ...

  • Photothermal quotient specifications to improve wheat cultivar yield component models

    Previous research has demonstrated the importance and statistical significance of the photothermal quotient (PTQ) to predict and explain wheat (Triticum aestivum L.) yields. The objective of this study is to respecify PTQ to enhance the explanatory power of statistical models used to explain grains per square meter (GM–2), and increase understanding of weather's impact on yields. The primary ...

  • An inflatable tunnel seal stops flooding of world`s largest undeveloped uranium mine

    The Cigar Lake Mine, located in the Athabasca Basin of Northern Saskatchewan, Canada, is sitting on the world's largest undeveloped high-grade uranium deposit in the world. Operated and majority-owned by Cameco Corporation, Cigar Lake is expected to eventually provide more than 10% of the world's mined uranium. But to extract the uranium ore, Cameco has to overcome significant technical ...
