Abstract
In this study, the muscle equivalent tissue models were
examined for unavoidable electromagnetic radiation from various devices which
used in daily life. Nowadays, daily exposure growing because of the increasing
use of electromagnetic field-emitting devices and their widespread diversity of
the frequency and power levels. Electromagnetic waves make different effects in
different frequencies and different strengths human body. This effect causes
some changes in body by heating or chemically. In this study, for different
frequencies such as 900 and 1800 MHz frequencies for mobile phone and 2.45 GHz
frequency for wireless communication devices and also the 27.12 MHz frequency
for medical devices, physiotherapy treatment (short-wave diathermy), muscle
equivalent liquid models are aimed for determining their effects on human
muscle tissue. Thermal changes in this phantom were measured for validation on
the model of electromagnetic exposure as well.

Abstract
Bu çalışmada günlük hayatta maruziyetinden sakınılamayan
farklı frekanslardaki cihazların oluşturduğu elektromanyetik yayılım için kas
eşdeğer modelleri oluşturulmuştur. Günümüzde elektromanyetik alan yayan
cihazların kullanımının giderek yaygınlaşması maruz kalınan frekans ve güç
seviyelerinin çeşitliliğini artırmaktadır. Elektromanyetik dalgalar farklı
güçlerde ve farklı frekanslarda, insan vücudunda değişik etkilerde
bulunmaktadır. Bu etkiler vücutta dokuları ısıtmakta veya kimyasal yoldan
değişimlere yol açmaktadır. Bu
çalışmada, 900 MHz ve 1800 MHz frekanslarındaki
cep telefonu, 2.45 GHz frekansındaki kablosuz haberleşme cihazlarının ve ayrıca
27.12 MHz frekansındaki tıbbi fizyoterapi tedavi cihazlarının (kısa dalga
diatermi) insan kas dokusu üzerindeki etkilerini belirlemek amaçlı kas eşdeğer
sıvıları oluşturulmuştur. Bu oluşturulan fantom model üzerinde elektromanyetik
maruziyetin neden olduğu ısıl değişimler ölçülmüştür.
