Engineering Assessment of the Potential Impact of Federal Radiation Protection Guidance on the AM, FM, and TV Broadcast Services

摘要

The report describes an engineering analysis of the potential impact of proposed EPA Federal Radiation Protection guidance for radiofrequency radiation on the broadcast industry. The study was performed by developing computer models of the radiofrequency radiation on the ground near broadcast stations and applying the models to data bases of the stations. The models were developed using theoretical predictions, empirical data and an existing numerical electromagnetic code, and compared with field study data and other prediction techniques to determine their accuracy. Variations of the models incorporating possible mitigation strategies were applied in conjunction with the original models so that the number of effective fixes could also be studied. Descriptions of the models and the results of the study are presented.
