Abstract

The radon concentrations in the groundwater, tap water samples and soil gases of the residential areas and forested lands of Uludağ were measured to research on the dynamics of low-high radon levels over the various rocks types found in this area. Besides, the annual effective doses for groundwater and tap waters were calculated and compared with the recommended dose value by the World Health Organization (WHO) to evaluate the health risk of inhabitant. The radon concentrations in water samples for the wet and dry seasons were found in the ranges of 0.17 ± 0.09 - 195.64 ± 6.87 Bq l-1 (median value of 5.13 Bq l-1) and 0.04 ± 0.01 - 199.24 ± 6.54 Bq l-1 (median value of 4.33 Bq l-1), respectively. Elevated radon concentrations were measured in the waters draining through igneous rocks (granite and granodiorite), known as uranium-rich rocks. The average radon and thoron concentrations of soil gases were found to be in the ranges of 0.65 ± 0.01 – 199.66 ± 3.27 kBq m-3 and 4.36 ± 0.36 – 245.9 ± 7.26 kBq m3, respectively. The highest and lowest radon and thoron concentrations in soil gases were observed in the granitic area and in scree region, respectively.

Özet

Uludağ’ın ormanlık arazileri ve yerleşim alanlarının toprak gazı, yeraltı ve musluk sularındaki radon konsantrasyonları, bu alandaki çeşitli kayaç tipleri boyunca düşük-yüksek radon seviye dinamiklerini araştırmak için ölçülmüştür. Ayrıca bu alanda yaşayan insanlar açısından sağlık riskini değerlendirmek amacıyla, musluk ve yer altı suları için yıllık etkin dozlar hesaplandı ve bu sonuçlar, Dünya Sağlık Örgütü (WHO) tarafından tavsiye edilen değerle kıyaslandı. Yağışlı ve yağışsız mevsimler için su örneklerindeki radon konsantrasyonları sırasıyla, 0.17 ± 0.09 Bq l-1-195.64 ± 6.87 Bq l-1 ( 5.13 Bq l-1 medyan değeri) ve 0.04 ± 0.01 Bq l-1-199.24 ± 6.54 Bq l-1 (4.33 Bq l-1 medyan değeri) aralıklarında bulundu. Yüksek radon konsantrasyonları, uranyumca zengin kayaçlar olarak bilinen volkanik kayaçlar (granit ve granitoyit) boyunca akan sularda ölçüldü. Toprak gazındaki ortalama radon ve toron konsantrasyonları sırasıyla 0.65 ± 0.01 – 199.66 ± 3.27 kBq m-3 ve 4.36 ± 0.36 – 245.9 ± 7.26 kBq m-3 aralıklarında bulundu. Toprak gazındaki en yüksek ve en düşük radon ve toron konsantrasyonları sırasıyla, granitik alanda ve yassı çakıl bölgede gözlemlendi.
