  • 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 ...

  • 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 ...

  • Value addition in diamonds and other gemstones by nuclear radiation: the phobias and safety considerations

    Four Cs, namely colour, clarity, carat (weight) and cut, primarily determine the price of a gem. Neutron irradiation, gamma rays and electron beams can be used to enhance the colour and clarity of aquamarine, quartz, tourmaline, kunzite, topaz, pearls and, most importantly, diamonds. Imparting colour and clarity to these gems that are otherwise devoid of these attributes results in significant ...

  • Chromosomal aberrations in Iranian radiation workers due to chronic exposure of X-irradiation

    The frequency of chromosomal aberrations in the peripheral blood lymphocytes of 65 radiology technologists working in hospitals in Tehran, Iran, who had been chronically exposed to X-rays, was analysed. Although film dosimetery did not show the maximal annual permitted dose (20 mSv per year) in any of the examined subjects, cytogenetic analysis detected fairly high levels of chromosomal ...

  • 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 ...

  • Detecting Hydrogen Gas and Fires: Seeing the Unseen

    Hydrogen usage is growing. The general public sees and reads about hydrogen as an alternative fuel for cars. However, the big use for hydrogen is found in hydrocarbon processing and other important manufacturing processes. Hydrogen is the first element on the periodic table and is an essential element in the manufacturing of many of our everyday products. We must have respect for its explosive ...

  • Continuous Real Time Water Monitoring for Radiation Safety Terrorist Attack, Improper Disposal of Industrial Waste, Accidental Discharge

    Safe drinking water is essential to life on earth. Unfortunately, this vast infrastructure suffers from critical vulnerability. Keeping America safe with continuous real time water monitoring is a vital goal and is currently being addressed for biological and chemical risks. For monitoring of radionuclides in drinking water as recommended in the Safe Drinking Water Act 8, the Clean Water Act 9, ...

  • Potential Repair of Escherichia coli DNA following Exposure to UV Radiation from Both Medium- and Low-Pressure UV Sources Used in Drinking Water Treatment

    The increased use of UV radiation as a drinking water treatment technology has instigated studies of the repair potential of microorganisms following treatment. This study challenged the repair potential of an optimally grown nonpathogenic laboratory strain of Escherichia coli after UV radiation from low- and mediumpressure lamps. Samples were irradiated with doses of 5, 8, and 10 mJ/cm2 from a ...

  • Upgrading from Pellistor Gas Sensors to Infrared Technology

    In this article Andy Avenell, Crowcon’s Fixed Systems Product Manager, considers the shift towards infrared (IR) gas sensor technology in the oil and gas industry. Abstract Flammable gases and vapours can present considerable dangers in many industrial applications, none more so than the processes involved in extracting, transporting and processing oil and gas. Fast and reliable ...

  • The application of Flow Injection Technology to automating cold vapor MERCURY analyses

    This document describes the application of flow injection technology to cold vapor mercury analyses. It can be obtained from PerkinElmer by requesting method number ENVA-100. Appendices 1 and 2 show letters from the US EPA indicating acceptability through the Alternate Test Program for both drinking water and wastewater sample analysis. 1.0 Scope and Application 1.1 This ...

  • Urban wastewater reuse: a pilot plant experience

    The results of a preliminary verification of domestic wastewater reusability in L'Aquila (Italy) are reported. A Tertiary Treatment Pilot Plant (TTPP), rotary filtration and Ultraviolet (UV) Radiation disinfection, was added to an Urban WasteWater Treatment Plant (UWWTP) to test the compliance with water quality indicated for reuse by the enforced Italian regulation. The TTPP was managed varying ...

  • Present Status and Future of Advanced Scientific Instrument using X-ray

    X-rays have attracted a lot of attention as a form of electromagnetic radiation that enable us to see objects through materials. And they are also a great contributor to clacification of physical phenomena. In the field of analysis, X-rays have drawn attention from their initial stage as a method of non-destructive simultaneous anaysis. Scientific measurement using X-rays is supported by three ...

  • Radiobiology worker risk assessment using stress indicators and proteomics

    Radiology is an essential technology in medicine and is used for organ diagnosis, radio–tracing and radiotherapy. The risks for the radiobiology workers have not been assessed sufficiently because measuring instruments fail to detect very low doses. This paper presents an investigation on the potential risks for radiobiology workers, due to the occupational exposure to low doses of irradiation. ...

  • 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 ...
