    FCC Cell Phone Safety Guidelines Underestimate Harmful Radiation Absorbed by Children and Small Adults, Says New Analysis

    READ FULL POST: http://electromagnetichealth.org/electromagnetic-health-blog/fcc-limit/

    A new paper published online today in Electromagnetic Biology and Medicine demonstrates children and small adults absorb significantly more cell phone radiation than had been previously understood by using the conventional and widely used assessment methodology, the Specific Anthropomorphic Mannequin (i.e. plastic model of a brain, or SAM), to assess the “Specific Absorption Rate”, known as the SAR.

    “ This study is important because it calls into question present cell phone exposure
    guidelines from an engineering, not health, point of view.
    “ Computer simulation of radiation penetration, in contrast to estimating radiation
    exposure using the fluid-filled plastic mannequin, demonstrates much greater
    radiation exposures, particularly for children and small adults, than previously
    “ The study shows that when phones are placed in the pocket or against the body
    the current FCC guidelines for radiation heating effects are presently being
    violated, and suggests that different SAR exposure guidelines should be
    established for people who are smaller than the mannequin, including children
    and smaller adults.
    “ Experts say it is unlikely many cell phones on the market today would pass the
    FCC certification process with the amount of radiation now being demonstrated
    with this methodology.
    “ The computer simulation methodology, known as Finite Difference Time Domain
    (FDTD), is an FCC-approved SAR assessment methodology. It offers 3 orders of
    magnitude higher resolution in the brain than the present methodology and can
    be used to measure radiation impacts on different parts of the body, as well,
    including especially sensitive tissues, such as the testes and the eyes.
    “ The higher resolution SAR assessment methodology, the FDTD, is presently
    used widely in research settings, including at the FDA.
    “ The authors of the new study (http://snurl.com/19xis1) recommend this more
    accurate cell phone radiation exposure methodology replace the SAM
    mannequin methodology.
    “ It is important to understand that globally accepted physics metrics are now
    indicating common cell phone use exposes users to radiation levels sufficiently
    powerful to cause tissue damage from heating.
    “ Previously, the focus of the cell phone safety debate has been on biological
    effects from the less well understood, but equally important, “non-heating” effects
    from the radiation, which are not addressed by either of the above risk
    assessment methodologies, and are a separate subject.
    “ Another issue, rarely discussed, is that our prevalent method of cell phone use
    (phone placed against the head) uses more energy from battery drain than
    communications using a wired headset. Using wired headsets not only will
    greatly reduce health risk, the subject of the current paper in Electromagnetic
    Biology and Medicine, but will also be more energy efficient on a very significant
    scale, given there are 5 billion cell phone users worldwide. On both grounds,
    governments have a mandate to act now to reconsider the mode in which we as
    a society use cellular communications.
    “ It is expected that governments globally will want to reassess the extent of cell
    phone proliferation, and especially use of cell phones by children, and to
    recommend wired headset use in light of this important re-analysis of cell phone
    radiation risk.

    “The higher risk of tissue damage from common cell phone use demonstrated in
    this study using the computer simulation method of SAR assessment suggests
    prudent public health policies, globally, would call for cell phones to be
    manufactured without the ability to use the phone against the head, nor with a
    speakerphone, but only allow communication with a wired headset. This would
    dramatically lower risk of biological, and genetic, damage to the population, and
    to children and other especially vulnerable populations, such as pregnant
    women, by keeping the radiation, thereby, away from both the head and body.”
