Measurements of RF radiation near MW and SW radio broadcast stations

Far field measurements of electric and magnetic fields in an area surrounding the MW and SW broadcast stations in Riyadh, Saudi Arabia are presented. Values of the electric fields contribution from each of the MW and SW stations separately are estimated. The variation of the electric field with height in a number of locations is also provided. All measured results are modeled by analytical expressions. They are then discussed and compared with the most up to date radiation safety standards. It is shown that RF radiation from strong MW and SW broadcasting stations could impose significant effects on environment outside the stations. Monitoring of the field levels for such sources should be carried out regularly.
