  • 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 ...

  • 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. ...

  • Brüel & Kjær’s radiation-resistant accelerometers

    Carrying out vibration measurements in harsh industrial environments is much easier for engineers with Brüel & Kjær’s new Type 8347-C Accelerometer. The Type 8347-C accelerometer can withstand temperatures ranging from -196°C (-321°F) to +482°C (+900°F) and has high resistance to radiation. The shear design ensures the accelerometer  superior thermal ...

  • Case study - Monitoring landfill gas

    Infrared absorption Infrared absorption is usually the preferred method for measuring methane and carbon dioxide. Most gases absorb radiation in the infrared region. The wavelength of radiation that is absorbed is determined by the natural vibration frequencies of the molecule. These natural frequencies will depend on several factors. Thus different gas molecules have different natural ...

  • Prevention measures against radiation exposure to radon in well waters: analysis of the present situation in Finland

    Naturally occurring radioactive elements are found in all groundwaters, especially in bedrock waters. Exposure to these radioactive elements increases the risk of cancer. The most significant of these elements is radon which, as a gas, is mobile and dissolves in groundwater. In Finland, water supply plants are obliged to carry out statutory monitoring of the water quality, including radon. ...

  • 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 ...

  • Wireless monitoring for a safe indoor environment

    This article discusses the benefits of wireless technology for continously monitoring the indoor environment. In striving for the construction of energy efficient and cost-effective buildings, the imperative issue of the buildings Indoor Air Quality (IAQ) is often overlooked. This can often lead to a unhealthy indoor environment and even to conditions such as Sick Building Syndrome (SBS) or other ...

  • Analox case study: Monitoring oxygen at Cranfield airfield

    Introduction For personnel safety, monitoring of oxygen levels was required as part of an experimental field campaign based at Cranfield airfield. This experiment was undertaken by researchers in the atmospheric physics group at Imperial College London. The researchers are interested in measuring Far-infrared radiance fields in the atmosphere ...

  • Safety in Drinking Water? Monitoring for Radioactive ContaminantsOnly Required Every Three, Six, or Nine Years per Federal Law

    Current federal law requires testing of drinking water for radionuclides, “hazardous radioactive materials” every three, six, or nine years. The states have the option to increase testing frequency. [Federal Register Year 2000; page 76746. http://www.gpoaccess.gov/fr/retrieve.html] An incident of terrorism, accident, or improper disposal ...

  • Monitoring the magnetic field in houses under 50 Hz high-voltage overhead transmission lines

    This paper deals with a one-week monitoring of the 50 Hz magnetic field on the ground floor and the first floor of houses under 150, 220 and 380 kV high-voltage overhead three-phase AC transmission lines. The field strength varied with the current intensity, the conductor height, and the storey of the house. Because current intensity varies with time the magnetic field depended on the time of day ...

  • Gas Detection in Public Swimming Pool Facilities

    Recreational facilities’ indoor swimming pools provide a venue for exercise, competition and fun for all ages as patrons splash, swim, dive and float around in the crystal clear water. To keep the water fit to swim in requires a disinfectant maintenance program commonly using Chlorine, or Chlorine and Ozone. Chlorine is a powerful, corrosive disinfectant and in both gas and liquid forms it ...

  • 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 ...
