Abstract

Transformers present
the most common source of exposure to excessive extremely low frequency (ELF)
magnetic fields (MFs). A transformer is an
electrical device that transfers electrical energy between two or more circuits
through electromagnetic induction. Nowadays the effects of
extremely low frequency electromagnetic (EM) fields on health have been
discussed frequently but there is few measurement studies performed around
various transformers for workers. In this
study, the leakage fields around transformers and enclosures site were measured in Ankara and evaluated
in terms of standards. It has been observed that people were exposed to ELF-MFs
above International Agency for Research on Cancer (IARC) cancer limits. Many
people reported health complaints such as being tired in most working hours,
immunological complaints, dizziness, some cancer cases are also observed there.
In these systems areas safe distances or areas for people should be realized
and precautions should therefore be
taken to minimize the fields exposed

Bir Çalışma Ortamında Bulunan Trafo Etrafındaki Oldukça Düşük Frekanslı Manyetik Alanların Ölçümü ve Risk Değerlendirilmesi

Abstract

Transformatörler, aşırı
düşük frekanslı (ELF) manyetik alanlara (MF'ler) maruz kalınan en yaygın kaynak
türü olarak karşılaşılmaktadır. Transformatör, elektromanyetik indüksiyon
yoluyla iki veya daha fazla devre arasında elektrik enerjisini aktaran elektrikli
bir cihazdır. Günümüzde oldukça düşük frekanslı elektromanyetik (EM) alanların
sağlık üzerindeki etkileri sıkça tartışılmıştır, ancak işçiler / çalışanlar
için çeşitli transformatörler etrafında yapılan birkaç ölçüm çalışması vardır.
Bu çalışmada, Ankara'da bulunan bir işyerinde trafo ve pano sahası etrafındaki
EM alanları ölçülmüş ve standartlar açısından değerlendirilmiştir. İnsanların
Uluslararası Kanser Araştırmaları Ajansı (IARC) kanser limitleri üzerindeki
ELF-MF'lere maruz kaldığı görülmüştür. Birçok insan çalışma saatleri içinde
yorulma, immünolojik şikâyetler, baş dönmesi, bazı kanser vakaları gibi sağlık şikâyetleri
olduğunu da bildirmiştir. Bu şekilde sistemlerin bulunduğu alanlarda insanlar
için güvenli mesafeler veya alanlar oluşturulmalı, maruz kalınan alanları en
aza indirmek için önlemler alınmalıdır.
