  • 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 ...

  • 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 ...

  • The influence of microwave radiation on the behaviour of Rattus norvegicus

    The use of mobile phones has been the target of a great controversy due to possible biological and behavioural effects. This research presents a preliminary evaluation, regarding the learning and stress levels in subjects of the species Rattus norvegicus, submitted to microwave radiation. The psychological analysis was based on laboratory tests using the aquatic maze (tank of Morris), to ...

  • New monitoring technology helps reveal Arctic secrets

    A group of Arctic researchers has employed the latest monitoring technology to investigate the effects of climate change, by measuring temperature and salinity in the water column beneath surface ice. The results of the investigation, which utilised YSI’s new 'Castaway-CTD', could cast new light on our understanding of the ways in which shifting ocean currents impact upon the climate in ...

  • U. S. Army Tests Water Monitoring Instruments for Deployed Troops

    The Army conducted a competition, TRE 10-1JCBRAWM, from July 12to July 24, 2010 at the White Sands Missile Testing Grounds, New Mexico, for the best detector for radiation in water. The participants were Technical Associates with their SSS-22P liquid scintillation monitor; Canberra with their iSolo silicon sample counter; and Hidex from Finland with a liquid scintillation counter. The competition ...

  • Detection and measurement of GWGs in semiconductor fab facilities

    Problem Statement Various processes and tools in the modern wafer fab plant produce effluent streams that contain unacceptably high levels of perfluorocarbon GWGs (greenhouse warming gases). These effluent streams are abated by plasma incineration and wet scrubbers and other techniques. It is necessary to measure the destruction removal efficiency (DRE) of the various abatement methods ...

  • The changing picture of greenhouse gas reporting for landfills

    With the implementation of Federal Mandatory Greenhouse Gas (GHG) reporting in 2010, landfill owners can find themselves subject to GHG reporting regulations at the federal level, and in some cases, also at the state or local level. This article will review the Federal Mandatory Reporting Rule (MRR) requirements for municipal solid waste (MSW) landfills subject to mandatory reporting under 40 ...

  • Closures of mine a new challenge for Romania

    AbstractThe mining activity is one of the oldest activity in Romania, dating from the year 100 B.C. The gold and silver ores represented one of the riches of our country. In time the economic content of metals diminuend, and the ore mines become non profitable. Due to this situation the best option of the State was the closure and ecological rehabilitation of the mines.The steps for the ...


  • UV disinfection for enhanced oil recovery and other oilfield applications

    One of the biggest challenges facing oil companies today is how to extract more oil from the discoveries made in the last 40 years. Estimates vary, but approximately 66% of the discovered oil gets left in the ground. The International Energy Agency has estimated that if, in the next 20 years, this figure could be reduced to 50%, then this would increase the world's recoverable oil by 1.2 trillion ...

  • Ozone Depletion and Global Warming Our Planet`s Protective Shield is Being Destroyed

    Ozone Depletion Stratospheric ozone is Earth's natural protection for all life forms, shielding our planet from harmful ultraviolet-B (UV-B) radiation. UV-B causes skin cancer, cataracts and immune suppression in both animals and humans. UV-B harms amphibian eggs, midge larvae and trout. UV-B also damages plants including hardwood forests, and phytoplankton (algae is a type of phytoplankton ...

  • Engineered wetland removes subsurface hydrocarbons while providing beneficial reuse

    British Petroleum (BP) is operating an engineered wetland to treat petroleum-contaminated groundwater at a 300-acre site in Casper, WY. Release of petroleum products during refinery operations from 1908 until 1991 resulted in significant petroleum hydrocarbon contamination. Over 44,000 yd3 of LNAPL were removed by dual-phase recovery wells and oil/water separators constructed in 1981, but ...
