In recent years, people
are often exposed to electromagnetic waves due to the increase of electromagnetic
devices such as satellite broadcasting systems, microwave ovens, induction
ovens, police and army radar systems and medical imaging modalities.
Particularly, the microwave sources used in industry have extreme effects on the
employee health. Because of inaccurate using of devices such as induction ovens
etc. or leakage from from devices, serious damages mayoccur in the brain, eye
and skin tissue of the person using the device. In this study, the SAR value
and temperature increase of tissues were computed by using multi layered tissue
model at the frequency ranges of 915, 2450 MHz which are operating frequencies
of industrial microwave sources. Analytical analysis were implemented using MATLAB
Software tool. The results were compared with medical safety limitsand observed
that they are under the limits.

ENDÜSTRİYEL MİKRODALGA KAYNAKLARA MARUZ KALAN ÇALIŞANLAR İÇİN ELEKTROMANYETİK RİSK ANALİZİ

Öz

Son yıllarda uydu yayın
sistemleri, mikrodalga fırınlar, indüksiyon fırınları, polis ve ordu radar
sistemleri, tıbbi görüntüleme gibi elektromanyetik cihazların kullanımının
hızlı bir şekilde artmasıyla insanlar sürekli elektromanyetik dalgalara maruz
kalmaktadır. Özellikle endüstride kullanılan yüksek güçlü mikrodalga kaynakları
çalışan sağlığı üzerinde ciddi riskler oluşturmaktadır. İndüksiyon fırını ve
buna benzer cihazların gerek hatalı kullanımı gerekse cihazlarda meydana gelen
kaçaklar nedeniyle cihazı kullanan operatörlerin beyin, göz ve deri dokusunda
ciddi hasarlar meydana gelebilmektedir. Bu çalışmada, endüstriyel mikrodalga
kaynaklarının çalışma frekansları olan 915 ve 2450 MHz frekanslarında dokularda
oluşan SAR değerleri ve sıcaklık artışı, çok katmanlı doku modeli kullanılarak
hesaplanmıştır. Analitik analizler MATLAB programı yardımıyla ayrı ayrı
yapılmıştır. Elde edilen sonuçlar, tıbbi güvenlik limit değerleriyle karşılaştırılmış
ve limit değerlerin altında olduğu tespit edilmiştir.
