Determination of Radionuclides and Elemental Concentrations in Black and White Tea Samples from Karadeniz in Turkey

Abstract

Tea is the second most consumed plant worldwide after water and it can be grown in humid climates. Considering the frequency of consumption, it is inevitable for the tea plant to become a very important field of study both in terms of commercial and public health. The tea plant appears in four different forms which are green tea, black tea, oolong tea and white tea depending on the production method. Especially white tea has started to attract the attention of science in recent years due to its antioxidant effect. The aim of this study is to examine radionuclides and elemental concentrations of black and white tea collected from Karadeniz in Turkey. Natural and artificial radionuclides concentrations were determined using gamma-ray spectrometry. 226Ra, 232Th, 40K, 137Cs were detected in both black and white tea samples. Elemental concentrations of the black and white tea were determined using energy dispersive x-ray fluorescence (EDXRF) spectrometry. Scanning electron microscopy (SEM) micrographs were obtained for black and white tea samples. 226Ra and 137Cs activity concentrations of black tea are higher than white tea however 232Th and 40K activity concentrations of white are higher than black tea. Total dose value of white is higher than black tea.

Türkiye Karadeniz Bölgesinden alınan Siyah ve Beyaz Çay Örneklerinde Radyonüklid ve Elementel Konsantrasyonlarının Belirlenmesi

Abstract

Çay, sudan sonra dünyada en çok tüketilen ikinci bitki türüdür ve nemli iklimlerde yetiştirilir. Tüketim sıklığı göz önüne alındığında çay bitkisinin hem ticari hem de halk sağlığı açısından çok önemli bir çalışma alanı haline gelmesi kaçınılmazdır. Çay bitkisi, üretim şekline göre yeşil çay, siyah çay, oolong çayı ve beyaz çay olmak üzere dört farklı biçimde karşımıza çıkar. Özellikle beyaz çay, antioksidan etkisi nedeniyle son yıllarda bilimin ilgisini çekmeye başlamıştır. Bu çalışmanın amacı, Türkiye'de Karadeniz Bölgesi’nden toplanan siyah ve beyaz çayın radyonüklitlerini ve elementel konsantrasyonlarını incelemektir. İncelenen örnek çayların doğal ve yapay radyonüklid konsantrasyonları gama ışını spektrometresi kullanılarak belirlendi. Hem siyah hem de beyaz çay örneklerinde 226Ra, 232Th, 40K, 137Cs konsantrasyon seviyeleri tespit edildi. Siyah ve beyaz çayın elementel konsantrasyonları, enerji ayırımlı x-ışını floresans (EDXRF) spektrometresi kullanılarak belirlendi. Siyah ve beyaz çay örnekleri için taramalı elektron mikroskobu (SEM) mikrografları elde edildi. Siyah çayın 226Ra ve 137Cs aktivite konsantrasyonları beyaz çaydan daha yüksek olduğu, ancak beyaz çayın 232Th ve 40K aktivite konsantrasyonlarının siyah çaydan daha yüksek olduğu görülmüştür. Beyaz çayın toplam doz değeri siyah çaya göre daha yüksek olduğu belirlenmiştir.
