Sandıklı havzası (Afyonkarahisar-Türkiye) içme sularında doğal radyoaktivite ve duraylı izotop özelliklerinin belirlenmesi

Öz

Sandıklı havzası Türkiye'nin güneybatısında yeralmaktadır. Bu makalede, Sandıklı havzasındaki akifer sisteminin beslenimini anlamak için yeraltısuyu duraylı izotop analizleri değerlendirilmiştir. Bu amaçla, havzada 2009-2010 yıllarında iki dönem boyunca yeraltısuları örnekleri toplanmış ve duraylı izotop ile doğal radyoaktivite analizleri yapılmıştır. Bölgedeki yeraltısularının δ¹⁸O ve δ²H içerikleri sırasıyla ‰-8.08 ile ‰-10.77 ve ‰-52.44 ile ‰-69.53 arasındadır. Duraylı izotop verileri genellikle Küresel Meteorik Su Doğrusu üzerindedir ve sular meteorik kökenlidir. Yeraltısularının trityum içeriği kurak dönemde 0.00-4.20 TU ve yağışlı dönemde 0.30-5.40 TU arasındadır. Trityum içeriğine göre yeraltısuları derin akifer ve yavaş dolaşımı göstermektedir. Yeraltısularındaki doğal radyoaktivitenin belirlenmesi insan sağlığı açısından önemlidir. Suların toplam alfa ve beta radyoaktivite konsantrasyonları 29-162 mBq L⁻¹ ve 70-330 mBq L⁻¹ arasında değişmektedir. Havzadaki içme sularında toplam α ve ß radyoaktivite konsantrasyonları nispeten düşük ve Dünya Sağlık Örgütü'nün içme suyu kriterlerine uygundur.

Determination of stable isotope characteristics and natural radioactivity in drinking waters in Sandıklı basin (Afyonkarahisar-Turkey)

Abstract

The Sandıklı basin is located in the southwestern part of Turkey. In this paper, groundwater stable isotope analyzes were evaluated to understand the recharge of the aquifer system in the Sandıklı basin. For this, samples of groundwater were collected for two periods in 2009-2010 years and the stable isotope and natural radioactivity analyzes were made in the basin. The δ¹⁸O and δ²H contents of groundwaters in the region range from -8.08 to -10.77‰ and from-52.44 to -69.53‰, respectively. The stable isotope data lie generally above the Global Meteoric Water Line and waters are meteoric origin. The tritium content of the groundwaters ranges from 0.00 to 4.20 TU in dry period and from 0.30 to 5.40 TU in rainy period, respectively. These δ³H values of waters could be represented that this waters are deep aquifer waters and slow circulation. The determination of the natural radioactivity in groundwater is important in terms of human health. The gross alpha and gross beta radioactivity concentrations of waters varied between 29-162 mBq L⁻¹ and 70-330 mBq L⁻¹, respectively. The results have shown that gross α and ß radioactivity concentrations in drinking waters in the basin are relatively low and suitable the World Health Organization regulations for drinking water.
