TASK FOR THE REPORT This committee has been tasked to provide an update of the 1979 Academy report that includes a discussion of: 1. The applicability of, and the level of uncertainty associated with, using data derived from cell, animal, and epidemiological studies employing continuous-wave exposure for evaluation of potential adverse health effects following phased-array exposures; 2.

UNCERTAINTIES INVOLVED IN USING NON-PHASED-ARRAY DATA FOR EVALUATION OF POTENTIAL ADVERSE HEALTH EFFECTS iFOLLOVVING PHASED-ARRAY EXPOSURES. There are a number of uncertainties associated with using data derived from cell, animal, and epidemiological studies employing continuous-wave and pulsed RF exposmes for evaluahon of potential adverse health effects in humans following phased-array exposures.

. in spite of the measurements and estimates of the PAVE PAWS waveforms and power densities, cunrently there are no data for estimating personal exposure at the level of an individual, · Using information on population density, topography, and direction of the PAVE PAWS radar beam, the cotntnittco estimated that the proportion of the population of upper Cape Cod whose primary residence is in direct line of sights to the PAVE PAWS beam was 11.~% m 1990 and 12.4% in 2000.

Since biological effects do not necessarily translate into adverse health effects, the implications of the biological observations are not known. At this time it is not known which characteristics of RF radiation at the power levels associated with the exposures to the general public from the PAVE PAWS radar, are biologically significant, if any.

studies on plant growth undertaken with radar exposures very similar to that of PAVE PAWS showed a dose- and distance-dependent decrease in tree growth, but there is currently no means for extrapolating from the biological responses reported in these studies to any health effect in humans. EPIDEMIOLOGY Epidemiology of Radiefrequency Exposures Other than PAVE PAWS · Studies reported in the peer-reviewed scientific literature describing health outcomes among human populations exposed to pulsed or continuous-wave radiefrequency exposures vary in scientific quality and provide conflicting results.

· The population size of upper Cape Cod places limits on the ability to conduct well-designed and well-conducted research to evaluate health outcomes associated with PAVE PAWS; however, moderately low levels of Increased risk rangrug between 40% and 100% (i.e., relative nsks between 1.4 and 2.0) could be investigated, with acceptable statistical power, for some of the more common forms of cancer.

While biological responses do not necessarily translate mto health effects, it is important to follow up on known biological effects to detennine if they relate to an identifiable health effect. Therefore, we suggest two types of biological studies: 1.
