The aim of this study is to
determine activity concentrations of natural and artificial radionuclides in
some commercial salt samples using HpGe gamma spectrometry system. In this
study, a total of 11 commercial salt samples which were 5-refined, 5-unrefined
and 1-dishwasher salt samples were examined. The activity levels of ²²⁶Ra,
²³²Th, ⁴⁰K and ¹³⁷Cs radionuclides, radium
equivalent activity, absorbed dose rate, annual effective dose equivalent,
annual effective dose values of ²²⁶Ra, ²³²Th and ⁴⁰K
from ingestion of salt samples for adults, 
internal hazard index and external hazard index were calculated in salt
samples. The obtained radium equivalent activity, absorbed gamma dose rate,
annual effective dose equivalent were compared with the average values given in
the international reports and it was concluded that the values of the salt
samples were lower than the average values stated in the international reports.
Annual effective dose values of ²²⁶Ra, ²³²Th and ⁴⁰K
from ingestion of salt samples for adults are higher than average values given
in the international report.

Bazı ticari tuz örneklerinde doğal ve yapay radyonüklitlerin aktivite konsantrasyonlarının belirlenmesi

Öz

Bu çalışmanın amacı bazı ticari tuz örnekleri içindeki doğal
ve yapay radyonüklitlerin aktivite konsantrasyonlarını HpGe gama spektrometre
sistemi kullanarak belirlemektir. Çalışmada 5-rafine edilmiş, 5-rafine
edilmemiş, 1-bulaşık makinesi tuzu olmak üzere toplamda 11 adet ticari tuz
örneği incelemiştir. Tuz örnekleri içindeki ²²⁶Ra, ²³²Th,
⁴⁰K and ¹³⁷Cs radyonüklitlerinin aktivite
konsantrasyonları, radyum eşdeğer aktivitesi, soğurulan gama doz oranı, yıllık
etkin doz eşdeğeri, ²²⁶Ra, ²³²Th ve ⁴⁰K doğal
radyonüklitlerin tuz örneklerinin yetişkinlerde yıllık tüketimden gelen etkin
doz değeri, iç tehlike indeksi ve dış tehlike indeksi değerleri hesaplanmıştır.
Elde edilen radyum eşdeğer aktivitesi, soğurulan gama doz oranı, yıllık etkin
doz eşdeğeri uluslararası raporlarda verilen ortalama değerler ile
karşılaştırılmış ve tuz örnekleri için elde edilen değerlerin, uluslararası
raporlarda belirtilen ortalama değerlerden düşük olduğu sonucuna ulaşılmıştır. ²²⁶Ra,
²³²Th ve ⁴⁰K doğal radyonüklitlerin tuz örneklerinin
yetişkinlerde yıllık tüketimden gelen etkin doz değeri, uluslararası raporda
belirtilen değerden daha yüksektir.
