Abstract (2. Language): 
The activity concentrations of natural gamma-emitting radionuclides in the samples of some commonly used building materials were measured by using a high resolution gamma-ray spectrometer. The results associated radiation hazard indexes due to 40K, 226Ra and 232Th were determined in samples collected from building material suppliers from southwest part of Turkey (Muğla). Different criterion formulas as radium equivalent activity, the external/internal hazard indices, the alpha/gamma indexes and the absorbed dose rate in indoor air were determined. Although indoor absorbed dose rate is relatively higher than the world population-weighted average value and international limit for studied brick and cement samples they could be used safely as building materials because radium equivalent activity, alpha/gamma indices and hazard indices of those materials have been found to be within the recommended limits. All the values for all criterion formulas for marble samples are found to be well below the safety limits recommended by UNSCEAR. It can be concluded that examined materials can be used for construction of buildings for interior and external works.

Abstract (Original Language): 
Bu çalışmada sık kullanılan bazı inşaat malzemelerinin içerdiği doğal gama yayıcı radyonüklitlerin aktivite derişimleri yüksek çözünürlüklü gama spektrometresi ile ölçülmüştür. Türkiye’nin güney batısında (Muğla) bulunan yapı malzemeleri tedarikçilerinden toplanan örneklerin 40K, 226Ra ve 232Th içeriklerinden kaynaklanabilecek radyasyon zararları belirlendi. Radyum eşdeğer aktivitesi, dâhili/harici zarar indisleri, alfa/gama indeksleri ve kapalı alanda absorplanan doz miktarları gibi farklı kriterler hesaplandı. Elde edilen sonuçlardan, çimento ve tuğla örneklerinin kapalı alan absorblanan doz miktarının dünya popülasyon ağırlıklı ortalamasından yüksek olduğu ancak radyum eşdeğer aktivitelerinin, dahili/harici zarar indislerinin ve alfa/gama indekslerinin önerilen maksimum güvenlik limitlerinin altında olduğu görüldü. Mermer örnekleri için ise tüm kriterlerin UNSCEAR tarafından önerilen güvenlik limitlerinin altında olduğu belirlendi. Sonuç olarak incelenen yapı malzemelerinin kullanımında insan sağlığı açısından bir sakınca olmadığı görüldü.
