I NEED HELP IN GATHERING PUBLISHED INFORMATION ABOUT THE RISKS POSED BY CELL TOWERS PLACED ON SCHOOL GROUNDS. THERE WHICH WOULD ENABLE ME TO GATHER/CALCULATE OR MEASURE RADIATION SPECIFIC SITE?
The best single reference is the Federal Communications Commission (FCC) Website. Look for: Bulletin 56, "Questions and Answers about Biological Effects and Potential Hazards of Radiofrequency Electromagnetic Fields," Bulletin 65, "Evaluating Compliance With FCC Guidelines for Human Exposure to Radiofrequency Electromagnetic Fields," "A Local Government Official's Guide to Transmitting Antenna RF Emission Safety: Rules, Procedures, and Practical Guidance." An excellent technical paper with field measurements of cell-tower emissions was published by R.C. Petersen and P.A. Testagrossa in the journal Bioelectromagnetics, volume 13, page 527ff, 1992. If you need onsite technical support and services there are various consultants available, such as Richard Tell Associates, Inc. Gary Zeman, ScD, CHP Lawrence Berkeley National Laboratory
