In this study, 32 different
commercially bottled mineral waters were collected from various regions of
Turkey.  Gross alpha and gross beta
activities of these bottled mineral water samples were measured by using
proportional counters. The gross alpha activity concentrations of 32 samples were
determined between Minimum Detectable Activity (MDA) (0.011-0.681 Bq/L) and 1.86 Bq/L with an average value of 0.541
Bq/L. Similarly, the gross beta activity concentrations were determined between
MDA (0.010-0.245 Bq/L) and 1.85 Bq/L with an average value of 0.813 Bq/L. The
gross alpha and gross beta activities of the mineral waters in Turkey
determined in this study were compared with the corresponding values of the
different countries.

            The results of the study showed that
the gross alpha and gross beta activities in all collected commercially bottled
mineral water samples except one are within the limits of regulations published
by Turkish Ministry of Health. Nevertheless, periodic monitoring of the mineral
waters is required to ensure the safe level in terms of radioactivity.

TÜRKİYE’DE ŞİŞELENMİŞ MİNERALLİ SULARIN TOPLAM ALFA VE TOPLAM BETA RADYOAKTİVİTE SEVİYELERİNİN BELİRLENMESİ

Bu çalışmada
Türkiye’nin çeşitli bölgelerinden ticari olarak şişelenmiş 32 farklı mineralli
su numuneleri toplanmıştır. Bu mineralli su numunelerinin toplam alfa ve toplam
beta radyoaktiviteleri orantılı sayaçlar kullanılarak ölçülmüştür. 32 farklı
numunenin toplam alfa radyoaktivite konsantrasyonu Ölçülebilir Minimum Değer (ÖMD) (0.011-0.681 Bq/L) ile 1.86 Bq/L
arasında değişen değerlerde ortalama 0.541 Bq/L olarak tespit edilmiştir.
Toplam beta radyoaktivite konsantrasyonu ise ÖMD (0.010-0.245 Bq/L) ile 1.85 Bq/L arasında değişen değerlerde
ortalama 0.813 Bq/L olarak tespit edilmiştir. Türkiye’de bulunan mineralli
sularda tespit edilen toplam alfa ve toplam beta aktivite değerleri farklı
ülkeler için yapılan benzer çalışmalarda bulunan değerler ile
karşılaştırılmıştır.

Bu çalışmada
elde edilen sonuçlara göre toplanan mineralli su numunelerinden bir tanesi
hariç diğer tüm numunelerde toplam alfa ve toplam beta aktivite
konsantrasyonları Türkiye Sağlık Bakanlığı tarafından yayınlanmış olan
yönetmelikteki limitlerin altında kalmıştır. Fakat yine de radyoaktivite
açısından güvenli seviyelerin devam ettiğinden emin olabilmek için mineralli
suların periyodik olarak izlenmesi gerekmektedir.
