🎯
Amaç & Hipotez:The gross a and b activity concentrations in the thermal waters of Karakaya-Ayaş, İçmece-Ayaş, Beypazarı (Dutluk-Tahtalı), Haymana, and Kızılcahamam spas in Ankara Province were measured by MPC-9604 multi-detector a /b counting system.
📊
Temel Bulgular & Veri:Ranges of activity concentrations found were from 0.09 to 2.58 Bq L-1 for gross a and from 0.25 to 2.61 Bq L-1 for gross b .

Özet

The gross a and b activity concentrations in the thermal waters of Karakaya-Ayaş, İçmece-Ayaş, Beypazarı (Dutluk-Tahtalı), Haymana, and Kızılcahamam spas in Ankara Province were measured by MPC-9604 multi-detector a /b counting system. Ranges of activity concentrations found were from 0.09 to 2.58 Bq L-1 for gross a and from 0.25 to 2.61 Bq L-1 for gross b . The ranges of minimum detectable concentrations for gross a (0.05--0.41 Bq L-1) and for gross b (0.04--0.29 Bq L-1) were obtained. Gross a and b activity concentrations found in samples were compared with the recommended guidelines of the World Health Organization and the Turkish Standards, and literature values. Na, K, Ca, Si, Mn, Ce, Te, Nd, Sm, Cs, W, La, U, and Th metal levels in these thermal ground waters were also determined by using wavelength dispersive X-ray fluorescence spectrometry (WDXRF).

Abstract

The gross a and b activity concentrations in the thermal waters of Karakaya-Ayaş, İçmece-Ayaş, Beypazarı (Dutluk-Tahtalı), Haymana, and Kızılcahamam spas in Ankara Province were measured by MPC-9604 multi-detector a /b counting system. Ranges of activity concentrations found were from 0.09 to 2.58 Bq L-1 for gross a and from 0.25 to 2.61 Bq L-1 for gross b . The ranges of minimum detectable concentrations for gross a (0.05--0.41 Bq L-1) and for gross b (0.04--0.29 Bq L-1) were obtained. Gross a and b activity concentrations found in samples were compared with the recommended guidelines of the World Health Organization and the Turkish Standards, and literature values. Na, K, Ca, Si, Mn, Ce, Te, Nd, Sm, Cs, W, La, U, and Th metal levels in these thermal ground waters were also determined by using wavelength dispersive X-ray fluorescence spectrometry (WDXRF).

Karakaya-Aya¸s 0.09 ± 0.02 0.25 ± 0.02 Present study ˙I¸cmece-Aya¸s 28 ± 0.06 0.47 ± 0.02 Present study Beypazarı 53 ± 0.11 43 ± 0.07 Present study Haymana 58 ± 0.22 82 ± 0.12 Present study Kızılcahamam 85 ± 0.13 61 ± 0.10 Present study Batman 91 097 1 Spain In this work, gross α and β activity concentrations and metal levels were determined in thermal ground waters of the Karakaya-Aya¸s, ˙I¸ cmece-Aya¸s, Beypazarı, Haymana, and Kızılcahamam spas. Some of the gross α and β results are higher than the guidelines given by the WHO for drinking water, but they are generally in agreement with the previously reported literature values. Gross α and β activity concentrations found were compared with the concentration levels of Th, U, or K in samples, but no linear relationship between them was observed. This detailed study may be the first on measurements of gross α and β activity concentrations and metal levels of thermal ground waters in Ankara and it may be used for the assessment of possible radioactivity changes in the future.
