Ms. Ayala referred to several items in the report by Micheal Kelsh that mentioned little research has been done on the RF emissions and that the report says 'we cannot eliminate all uncertainty ". Micheal Kelsh, Environmental Health Strategies, the consultant retained by the City, said there have not been a lot of studies done on human population. He said scientists are often asked to provide a black and white answer. There is no black and white answer. No scientist could stand up today and say categorically there will never be research in the future showing that the levels have no effect on people. Ms. Ayala asked if he would live within fifteen feet of a tower and if it bothered him that studies have only just begun. Mr. Kelsh said he would look at all the literature and determine if there was a reason to be concerned. The studies thus far cannot prove there is any significant effect. There is however, more adverse effect from cellular phones than there would be from these towers. Ms. Michelotti asked if he agreed with the charts in the reports. Mr. Kelsh said yes he agreed. Mr. Bushberg said exposure from cordless phones would be the same as the maximum levels indicated in the studies. He said the levels from a baby monitor are about the same as from a typical PCS, or 1 to 2 microwatts. He stated again there are other things that might have a more adverse effect on humans than these towers. Mr. Kelsh said it is not uncommon for earlier studies to give way to later studies. Mr. Pico asked how close were children living to the towers in the earlier studies. Mr. Kelsh said two factors affect the exposure. One is their height relative to the antenna and the other is the horizontal separation between the antenna and where the person is located. Housing will provide protection against these transmissions. Carrie Takeyasu, 6483 Chabot Drive, Suite 100, presented slides showing the proposed sites. She gave a brief overview on how the site was picked. Many factors are looked at when picking a site, such as existing sites, radio frequency emissions to serve an area, sites not too close to other sites, and elevation. Julie Skidmore, 20855 Waterford Place, Castro Valley, 94552, gave a brief overview of the project description. She said Cellular One has determined there is a need for these towers in Pleasanton in order to serve Pleasanton customers. Pleasanton City Council 9/2/97 Minutes 16
