All living things are constantly exposed to ionizing radiation emitted from natural and artificial radiation sources present in the world throughout their lives. Therefore, it is very important to determine the radioactivity levels of the products that people use and the environment they live in. In this context, 12 baby powder samples of different companies were obtained from local markets. The concentrations of 226Ra, 232Th and 40K in the powder samples were measured using a high purity germanium detector (HPGe). It was determined that 226Ra, 232Th and 40K radioisotope concentrations in the examined powder samples ranged between 2.31-12.71 Bq/kg, 1.26-13.68 Bq/kg and 4.69-38.21 Bq/kg, respectively. The average 226Ra, 232Th and 40K radioactivity concentrations in the powder samples were 5.11 ± 0.81 Bq/kg, 4.17 ± 0.59 Bq/kg and 17.30 ± 1.59 Bq/kg, respectively. To assess the radiological hazards from natural radioisotopes in the examined powder samples, the annual effective dose values (YED) was calculated and compared with the average values recommended by reputable international organizations. As a result, it was determined that the use of the examined powder samples would not pose a radiological risk.

Bebek pudralarında doğal radyoaktivite ve radyolojik risklerin değerlendirilmesi

Öz

Tüm canlılar yaşamları boyunca sürekli olarak dünyada mevcut olan doğal ve yapay radyasyon kaynaklarından yayımlanan iyonlaştırıcı radyasyona maruz kalmaktadır. Bu nedenle, özellikle insanların kullandıkları ürünler ve yaşadıkları çevrenin radyoaktivite seviyelerinin belirlenmesi oldukça önemlidir. Bu kapsamda, yerel marketlerden satışa hazır farklı firmalara ait 12 adet bebek pudrası örneği temin edildi. Pudra örneklerinde 226Ra, 232Th ve 40K konsantrasyonları yüksek saflıkta germanyum detektörü (HPGe) kullanılarak ölçüldü. İncelenen pudra örneklerinde 226Ra, 232Th ve 40K radyoizotop konsantrasyonlarının sırasıyla 2.31-12.71 Bq/kg, 1.26-13.68 Bq/kg ve 4.69-38.21 Bq/kg aralığında değiştiği belirlendi. Pudra örneklerinde ortalama 226Ra, 232Th ve 40K radyoaktivite konsantrasyonları sırasıyla 5.11 ± 0.81 Bq/kg, 4.17 ± 0.59 Bq/kg ve 17.30 ± 1.59 Bq/kg olarak bulundu. İncelenen pudra örneklerindeki doğal radyoizotoplardan kaynaklanan radyolojik tehlikeleri değerlendirmek için yıllık etkin doz değerleri (YED) hesaplandı ve saygın uluslararası kuruluşlar tarafından önerilen ortalama değerlerle kıyaslandı. Sonuç olarak, incelenen pudra örneklerinin kullanılmasının radyolojik olarak bir risk oluşturmayacağı belirlendi.
