Abstract

The main purpose of environmental radioactivity measurements is to determine the radiation dose that people receive from natural sources and the effects on human health. The greatest contribution of the average dose received by humans comes from natural radiation (86%). The average annual effective dose from natural radiation sources is 2.4 mSv. Most of this dose is the radionuclides ( 238 U, 232 Th and decay products and 40 K) that have existed since the formation of the world. In recent years, study to determine the radiation doses that people receive from natural sources has been intensified. There are many studies that are concerned radioactivity and the rate of radiation of the coastal line in the various regions of the world. However, there are not enough studies in Turkey. In this study, the activity concentrations of natural radionuclides ( 226 Ra, 232 Th, 40 K) of beach sand samples taken along the coastline of Urla district were measured by HPGe gamma spectrometry system and the dose rates exposed by people living in this area were calculated. The results obtained are compared with the world average and studies conducted in different provinces. It is seen from the results that the gamma dose rates of the Urla district coastline are not a risk for human health.

Özet

Çevresel radyoaktivite ölçümlerinin temel amacı, insanların doğal kaynaklardan aldıkları radyasyon dozunun tayini ve insan sağlığı üzerindeki etkilerinin belirlenmesidir. İnsanlar tarafından alınan ortalama doza en büyük katkı, doğal radyasyondan gelmektedir (%86). Doğal radyasyon kaynaklarından alınan yıllık ortalama etkin doz 2.4mSv’dır. Bu dozun büyük bir kısmını dünyanın oluşumundan beri var olan primordial radyonüklitler ( 238 U, 232 Th ve bozunum ürünleri ve 40 K) oluşturmaktadır. İnsanların doğal kaynaklardan aldıkları radyasyon dozlarının belirlenmesine yönelik çalışmalar son yıllarda yoğunluk kazanmıştır. Kıyı şeridinin radyoaktivitesi ve doz hızları ile ilgili dünyanın çeşitli bölgelerinde birçok çalışma yapılmıştır. Fakat Türkiye’de yeterli sayıda çalışma bulunmamaktadır. Bu çalışmada, Urla ilçesinin kıyı şeridi boyunca alınan plaj kumu örneklerinin doğal radyonüklit ( 226 Ra, 232 Th, 40 K) aktivite konsantrasyonları HPGe gama spektrometre sistemi ile ölçülmüş ve bu bölgede yaşayan insanlar tarafından maruz kalınan doz hızları hesaplanmıştır. Elde edilen sonuçlar, dünya ortalamaları ve farklı illerde yapılan çalışmalarla karşılaştırılmıştır. Sonuçlardan görülmüştür ki, Urla ilçesi kıyı şeridinin gama doz hızları insan sağlığı açısından bir risk oluşturmamaktadır.
