  • Buying a New Home

    Buying or renting a new home? Would you like a home that has low electromagnetic fields - a home that's a safe environment for your family to grow ...
  • Residential exposure

    New Australian study investigates magnetic field exposures in homes Australian investigators have shown that high magnetic fields are often found i...
  • dB (decibel) – what does it mean?

    Units of measurements called decibels (dBs) are often used to denote how much reduction (attenuation) of signal strength has occurred after shieldi...
  • Australian radiation standards – do they protect us?

    The Australian standard and Guidelines of the International Commission on Nonionizing Radiation Protection (ICNIRP) are based on a number of premis...
  • Scientist call on world authorities to protect from radiofrequency radiation.

    The Advisors to the International EMF Scientist Appeal, representing 248 scientists from 42 nations, have resubmitted The Appeal (below) to the Uni...
  • Body voltage - should it be measured?

    Should you use earthing products and should you measure body voltage? Alasdair Phillips, director of EMFields and Powerwatch and designer of the EMFields meters we stock, shared his views with us. Alasdair is an internationally-respected authority on testing electromagnetic fields. He said: 'I have real problems with the measurement of “body voltage” as it is usually measured and I need to answer it in a somewhat long-winded way. 
  • Exposure in public places

    To discover how much wireless radiation people are exposed to in public spaces, Swedish researchers measured the fields present in the Stockholm Central Railway Station in Sweden. They took measurements in over 1600 locations and found that exposures measured bwtween 2,817 and 4,891 uW/m2. That's a much higher exposure than the 3-6 uW/cm2 recommended by the independent authors of the BioInitiative Working Group.
  • WiFi in homes and schools

    When it comes to WiFi, are we exposed to more radiation from routers in schools or in homes? This is what electrical engineer and Director of Powerwatch has to say: (a) The school routers that I have measured have not been worse (i.e. more powerful) than home routers per se. There are also often many of them (1 to 3 routers per classroom or hall are common) which increases the RF power density.

  • EMR and depression

    Electromagnetic fields affect calcium channels, increasing calcium levels in cells and triggering a chain of events that leads to symptoms such as depression, according to Professor Martin Pall. This occurs at nonheathing (athermal) levels of exposure - ie levels that comply with Australian and international standards.
  • Techitis

    Constant use of smart phones is negatively affecting people's health, say experts. Eyesight problems, muscle and joint pain, tissue degeneration and fatigue are all symptoms that have been linked to people's phone use.
  • Mobiles and cancer

    A recent paper by Professor Simon Chapman claims that there is no increased rate of brain tumours in Australia that correlates with increased use of mobile phones. Following the publication of this paper, a number of articles have appeared, suggesting that mobile phones don't increase brain tumour rates.
