Overview

The following summary of projects is intended to be illustrative of the kinds of work that Richard Tell Associates, Inc. has been engaged in during the past 14 years of private consulting practice. Accordingly, this list is selective and not exhaustive but should provide the reader with a good idea of the level of experience and expertise available from Richard Tell Associates. Hopefully, it will also be educational. Prior to entering into his own consulting business focused on RF safety issues, Mr. Tell acquired 20 years of experience in U.S. Federal government service (Environmental Protection Agency and FDA) working in the areas of electromagnetic fields and RF hazard assessment, RF standards development, antenna modeling and RF instrumentation evaluation. NOTE: All photographs and graphic illustrations contained in this project summary document show project locations, measurement procedures, equipment, analysis results, etc. associated with actual projects conducted by Richard Tell Associates, Inc.
