Research that could further understanding of long-term low exposure to radio frequency (RF) energy from wireless communication devices is the topic of a National Research Council report sponsored by the US Food and Drug Administration. It identifies research needs based on presentations made by international experts and discussion sessions at a three-day workshop last August that evaluated topics such as measurement of RF energy and exposure, studies on human populations, human laboratory measurements, and animal and cell biology. Copies of "Identification of Research Needs Relating to Potential Biological or Adverse Health Effects of Wireless Communications Devices" are available from the National Academies Press; phone: (202) 334-3313 or (800) 624-6242, or visit: www.nap.edu
