  • Influence of Voids on Density Measurements of Granular Materials Using Gamma Radiation Techniques

    The use of gamma radiation equipment for the nondestructive measurement of soil density originated nearly four decades ago. The typical procedure involves a careful calibration of the gamma radiation counts on specimens of known density of the same materials as those whose density are to be measured. This paper presents the results of laboratory gamma-ray density measurements on 100-mm-diameter ...

  • Radioactive Clean-up

    Radioactive, nuclear, or radiation clean-up is considered as the most dangerous, difficult, and costly remediation activity after a nuclear disaster or accident.  The contamination may be found in the air, water, and soil, as wells as equipment and buildings (USEPA, 2010). Radioactive material is unstable, while the nuclei of radioactive atoms emit ionizing radiation (i.e., alpha ...

Over time, the nuclei of radioactive atoms emit what's ...

  • LIMS is the Anchor for Next-Gen Mining - News from MINExpo 2012

    Thermo Fisher Scientific, Inc. exhibited its Next-Gen Mining portfolio during MINExpo 2012 in Las Vegas, September 24-26. The company’s highly integrated range of instruments, equipment and consumables, anchored by its industry-leading laboratory information management systems (LIMS), is the only offering that addresses all segments of the mining process, from early stage exploration ...

  • 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 ...
