Longterm Electromagnetic Field Measurements and Pollution Maps in a University Campus

Öz

Electric field intensity emitted by electromagnetic field sources of the base stations in the campus of Inonu University and other very high frequency electromagnetic field sources' spread which are effect above at campus field were done and the frequency-based electromagnetic intensity maps of the campus were prepared. According to achieved measurement conclusions, the results were evalauted by comparing the periodical changes. The field intensity values of the electromagnetic waves which have different frequencies were measured by making a spectrum analysis over 450 points in the range of 27MHz-3GHz frequency in 2011. Also, in 2013, electric field intensity values were measured with instant measurements over 6700 points in the range of 100kHz-8GHz frequency. The electromagnetic pollution maps were drawn with obtained electric field values and the results were evaluated. One of study aims, it was determined changing electric field intensity along two-year period in campus of university. Another one purpose is provided homogeneous distribution of electric field source at this area with electromagnetic pollution maps which are drawn by obtained datas from results of measurements, and determined possible risk areas.

Bir Üniversite Yerleşkesinde Uzun Süreli Elektromanyetik Alan Ölçümleri ve Kirlilik Haritaları

Öz

İnönü Üniversitesi yerleşke alanında bulunan baz istasyonlarının ve kampüs yerleşkesi üzerine etki eden diğer çok yüksek frekanslı elektromanyetik alan kaynaklarının yaydığı elektrik alan şiddetlerinin dönemsel ve uzun süreli ölçümleri yapılmış, yerleşkenin frekans bazlı elektromanyetik alan yoğunluk haritaları çıkarılmıştır. Elde edilen ölçüm sonuçlarına göre dönemsel değişimler kıyaslanarak sonuçlar değerlendirilmiştir. 2011 yılında 27 MHz-3GHz frekans aralığında spektrum analizi yapılarak yerleşke dâhilinde 450'nin üzerinde noktada, farklı frekanslara sahip elektromanyetik dalgaların alan şiddeti değerleri ölçülmüştür. 2013 yılında 100 kHz-8 GHz frekans aralığında anlık ölçümler ile 6700'ün üzerinde noktada elektrik alan şiddeti değerleri ölçülmüştür. Elde edilen sonuçlarla, elektromanyetik alan kirlilik haritaları çizilmiş ve sonuçlar değerlendirilmiştir. Çalışmanın amaçlarından biri iki yıllık periyotta üniversite yerleşkesinde elektrik alan şiddetinin değişiminin belirlenmesidir; bir diğer amacı da ölçüm sonuçlarından elde edilecek verilerle çizilen elektromanyetik kirlilik haritaları ile bu bölgedeki elektrik alan kaynaklarının homojen dağılımının sağlanması ve olası risk bölgelerinin belirlenmesidir.
