Abstract AR
تتناول هذه الورقة العلمية موضوع القياسات الميدانية لكثافة القدرة للإشعاع اللاسلكي في الأماكن المجاورة لمحطة بث تحتوي على مرسلات إذاعية من نوع (FM) و مرسلات تلفزيونية عند نطاق VHF، و قد وجد أن أقصى قيمة مناسبة هي حوالي μW / cm2 2.4 على ارتفاع مترين من سطح الأرض أما المتوسط فكان μW / cm2, 1 و تبين أن كثافة القدرة للإشعاع اللاسلكي تتزايد مع الارتفاع عن سطح الأرض حتى تصل إلى قيمة μW/cm2 3.4 عند ارتفاع 15 مترا.
و في موقع يبعد عن المحطة بمسافة 400 متر.
و في موقع آخر يبعد عن المحطة بمسافة 185 متر، كانت كثافة القدرة المقاسة حوالي μ W / cm2 41 و ذلك على ارتفاع 18 متر من سطح الأرض.
Abstract EN
This paper provides measurements of power density around an FM and VHF-TV broadcasting station and its variation with distance.
The maximum measured value was about 2.4 μ W / cm2 at a height of 2 meters above ground level while the average value was fluctuating around 1 μ W / cm2.
It was found that the measured power density increases with height above ground and it reaches about 3.5 μ W / cm2 at a height of about 15 meters at a location of about 400 meters from the station.
At a nearer distance of 185 meters from the tower another measurement was taken at a height of 18 meters, the power density increased to 41 μ W / cm2.
