Öğe Siirt ilinin içme sularında toplam alfa ve beta aktivitesi(Batman Üniversitesi, 2016) Altun, Ahmet; Damla, NevzatGüneydoğu Anadolu Bölgesinde yer alan Siirt ili kendine özgün tarihi ve kültürel farklılıklarıyla tercih edilen bir turizm durağıdır. Bu çalışmada, 12 farklı musluk suyu örneklerindeki toplam alfa ve beta aktivite derişimleri, Berthold LB 770 model çok detektörlü düşük seviyeli gaz orantılı aynı anda on ölçüm yapabilen sayım cihazı kullanılarak ölçülmüştür. Ölçümleri yapılan toplam alfa ve beta aktivite derişim değerleri tablo ve şekiller halinde verilmiş olup WHO ve TSE yönetmenlikleri tarafından tavsiye edilen limit değerler ile karşılaştırılmıştır. Toplam alfa ve beta aktivite derişim değerlerinin, sırasıyla 9 ± 5 – 40 ± 9 mBq/L ile 21 ± 11- 252 ± 23 mBq/L arasında değiştiği bulundu. Analizleri yapılan musluk sularının sindirilmesi nedeniyle oluşabilecek radyolojik riskleri, yetişkin bireyler için değerlendirmek amacıyla, yıllık etkin doz değerleri WHO tarafından önerilen doz dönüşüm katsayıları kullanılarak hesaplanmıştır. Hesaplamalar sonucunda 238U, 226Ra, 210Po, 210Pb, 228Ra ve 232Th'nın ortalama doz değerleri sırasıyla 0,9, 5,3, 22,6, 52,3, 52,3 and 4,3 Sv/y' olarak bulundu.Öğe 238U and total radioactivity in drinking waters in Van province, Turkey(Taylor & Francis, 2014-04) Selçuk Zorer, Özlem; Dağ, BeşirAs part of the national survey to evaluate natural radioactivity in the environment, concentration levels of total radioactivity and natural uranium have been analysed in drinking water samples. A survey to study natural radioactivity in drinking waters was carried out in the Van province, East Turkey. Twenty-three samples of drinking water were collected in the Van province and analysed for total α, total β and 238U activity. The total α and total β activities were counted by using the α/β counter of the multi-detector low background system (PIC MPC-9604), and the 238U concentrations were determined by inductively coupled plasma-mass spectrometry (Thermo Scientific Element 2). The samples were categorised according to origin: tap, spring or mineral supply. The activity concentrations for total α were found to range from 0.002 to 0.030 Bq L−1 and for total β from 0.023 to 1.351 Bq L−1. Uranium concentrations ranging from 0.562 to 14.710 μg L−1 were observed in drinking waters. Following the World Health Organisation rules, all investigated waters can be used as drinking water.Öğe Correlation of nutritional element levels in drinking water with body compositions of women aged 55-70 years living in Batman province(Dicle Üniversitesi, 2017-02-02) Çetin, İhsan; Nalbantçılar, Tahir; Güler Saban, Meryem; İnci, Ramazan; Tosun, Kezban; Nazik, AydanObjective: A growing interest in cellular targets of nutritional minerals and biochemical mechanisms has attracted the attentions of researchers towards their role in formation of obesity. However, there is no study investigating the effects of nutritional element levels of drinking water on body composition of the elderly. Therefore, we aimed to examine the effects of nutritional element levels in drinking water on body composition of women aged 55-70. Methods: The study population consisted of 80 participants in total, and was divided into three groups as overweight, obese and control women aged between 55-70. The bioelectric impedance device was used for measurements of body composition of the participants. Iron (Fe), copper (Cu), cobalt (Co), zinc (Zn), manganese (Mn) and selenium (Se) levels of drinking water were measured via plasma mass spectrometry coupled inductively. Results: It was found that Se mineral content in drinking water correlated with the body mass index of the individuals living in Batman, Turkey. Moreover, it was found that Fe, Cu, Co, Zn, Mn and Se levels of drinking water significantly correlated with the abdominal adiposity of women of 55-70. Conclusion: It may be suggested that the obesity risk may be higher in women who are between 55-70 and consume drinking water with high levels of Fe, Cu, Co, Zn, Mn and especially Se.
