These needs and gaps are committee judgments derived from the workshop presentations and discussions, and the report does not necessarily reflect the views of the FDA, individual workshop speakers, or other workshop participants.

The committee judged that important research needs included, in order of appearance in the text, the following:

  • Characterization of exposure to juveniles, children, pregnant women, and fetuses from personal wireless devices and RF fields from base station antennas.

  • Characterization of radiated electromagnetic fields for typical multiple-element base station antennas and exposures to affected individuals.

  • Characterization of the dosimetry of evolving antenna configurations for cell phones and text messaging devices.

  • Prospective epidemiologic cohort studies of children and pregnant women.

  • Epidemiologic case-control studies and childhood cancers, including brain cancer.

  • Prospective epidemiologic cohort studies of adults in a general population and retrospective cohorts with medium to high occupational exposures.

  • Human laboratory studies that focus on possible adverse effects on electroencephalography2 activity and that include a sufficient number of subjects.

  • Investigation of the effect of RF electromagnetic fields on neural networks.

  • Evaluation of doses occurring on the microscopic level.

  • Additional experimental research focused on the identification of potential biophysical and biochemical/molecular mechanisms of RF action.


Electroencephalography is a neurological diagnostic procedure that records the changes in electrical potentials (brain waves) in various parts of the brain.
