  • 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. ...

  • Visual and thermal comfort and its relations to exergy consumption in a classroom with daylighting

    This paper discusses the exergetic aspect of daylighting together with luminous and thermal comfort aspect. We calculated the exergy consumption for lighting and cooling in a classroom for the cases with and without electric lighting. The full use of daylighting decreases chemical exergy input to the power plant by 89%. According to a questionnaire survey asking the students' perception of ...

  • GPR antenna resolution

    How many antennas should I have? We have all heard that question, especially coming from the newcomers to the Ground Penetrating Radar (GPR) technology. The people starting to master this technology are amazed that one has to have so many different antennas for what appears to be the same thing, scrutinizing the earth. What antenna(s) should I choose? ...

  • Knowledge survey based on published works in the area of WWER reactor pressure vessel steels microstructure

    The effects of intensive fluxes of neutrons, thermal ageing or other external factors result in considerable changes of material microstructures and properties. In particular, the development of the fine scale radiation-induced defects which impede the dislocation motion under the applied stress, known as the irradiation embrittlement, leads to mechanical properties degradation which can results ...

  • A Monte Carlo simulation of a whole body counter

    The preparedness of response to the accidental incorporation of radionuclides into the human body by inhalation or ingestion is a subject of major concern due to the generalised use of ionising radiations in medical and industrial applications. Following a radiological or nuclear accident or in case of occupational exposure due to an accidental dispersion of radionuclides, a rapid methodology is ...

  • Gamma-Radiometric assessment of soil depth across a landscape not measurable using electromagnetic surveys

    Soil depth affects plant available soil water storage capacity (PAWC). This storage capacity is important for grain yield, deep drainage, and nitrate leaching in dryland environments but is difficult to measure directly on a broad scale. Measurements of ECa provide a means of estimating soil depth at spatial resolution of <50 m when sufficient contrast in conductivity exists between the ...

  • The 2007 Marie Curie prize: the linear no threshold relationship and advances in our understanding of carcinogenesis

    Better knowledge of carcinogenesis has improved the assessment of the putative carcinogenic effects of low doses of Ionising Radiation (IR). Cancer induction is a main threat to multicellular organisms and safeguards have been introduced during evolution. Mutations result from endogenous agents, mainly Reactive Oxygen Species (ROS), and exogenous agents. IR and solar ultraviolet (UV) have existed ...

  • 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. ...

  • Nuclear/radiological emergency response in the USA

    The US Consequence Management (CM) response element uses specific methodologies for dealing with the release of nuclear/radioactive material into the environment and has identified the potential impacts to the public and the environment. This paper will describe the history of how CM evolved, an overview of the current methods and response structure and include technical sections describing the ...

  • Aerial radiological systems, measurements and analysis

    This document describes data collection systems and procedures used by the US Department of Energy Aerial Measuring System (AMS) in response to a radiological emergency. The discussion is split into two parts: (1) those systems used on the fixed-wing aircraft and (2) those systems used on the helicopters. This split is principally caused by the final use of the data from each system. The ...

  • Principal provisions of engineering and geological survey methodology in designing and construction of underground laboratory as a part of facility of RW underground isolation

    The most critical moment is the choice of a site for radioactive waste geological repository. Here the role of engineering and geological prospecting as a basis for the construction of a facility for underground isolation appears especially important; it is followed by finding a suitable area and subsequent allocation of the site and facility construction sites. The decision on the selection of ...

  • 210Po concentration in urine of residents in a high level background radiation area in Iran

    As part of an epidemiological survey to determine public exposure to natural radiation and to estimate radionuclide levels in the diet of residents in a high level background radiation area at Ramsar in Iran, 210Po concentrations were determined in 24-hour urine samples by means of a liquid scintillation counting technique. The maximum and minimum mean concentrations of ...

  • DNA repair in nuclear workers after occupational exposure to ionising radiation

    Recently, for purposes of radiation safety, the validation of the linear non-threshold (LNT) hypothesis at low doses of radiation was actively discussed. New knowledge, especially on subcellular level, might contribute to the clarification of this problem. The aim of our study was to describe the patterns of spontaneous (rs_sp) and induced (rs_ind) leukocyte DNA repair in workers from the Nuclear ...

  • 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 ...
