RF exposure in a shortwave transmitter environment including the influence of building structure and human body

According to a Swiss government survey (1993) RF exposure in a shortwave environment might be a source of insomnia, reduced concentration, high blood pressure and a general anxiety. The study performed specialised measurements and numerical predictions of the electromagnetic environment near the shortwave transmitter `Schwarzenburg' including an investigation of the RF exposure inside buildings and bedrooms. In a further step the influence of the human body on field distribution and attenuation was calculated. This allowed certain measurement guidelines and precautions to be deduced. The paper gives an overview of the gathered RF exposure data and concentrates mainly on specialised measurement techniques and related problems.
