“…Standard solutions of potassium prepared from KCl (Merck) and KI (Sigma-Aldrich) standard solution and deionized water were utilized for validation of this method. The minimum detectable activity concentration (MDAC) for the γ-ray measurement system was calculated by the following equation. , where F C is the statistical coverage factor equal to 1.64 (confidence level 95%) and B is the background counts over the region of interest for each radionuclide . The MDAC values for the radionuclides of interest were calculated as 0.2, 0.3, and 1.9 Bq/L for 226 Ra, 228 Ra, and 40 K, respectively.…”

Bottled natural mineral water (BMW) consumption in Turkey is increasing every year. Depending on the local geology from which the water is extracted, BMW could be enhanced with natural radionuclides. In this study, the activity concentrations of natural radionuclides in 58 BMW samples of 25 different brands marketed in Turkey were measured using a γ-ray spectrometer with high-purity germanium (HPGe) detector. The average activity concentrations of 226 Ra, 228 Ra, and 40 K in BMW samples were found as 0.4, 0.5, and 4.3 Bq/L, respectively. The activity concentrations of 228 Ra exceeded the WHO-recommended maximum permissible limit of 0.1 Bq/L for drinking water. The annual effective dose (AED) and excess lifetime cancer risk (LCR) caused by the ingestion of each BMW sample were estimated for adults to assess radiological risks using two different scenarios based on BMW consumption rates (150 and 13 L/y). All estimated total AEDs, except for two samples, were below the guidance dose level of 100 μSv/y recommended by the World Health Organization (WHO) and Turkish regulations for drinking water. For all BMW brands, 228 Ra was found as the main contributor to the AEDs. The LCR values were lower than the acceptable value of 10 –3 for radiological risks.

Anahtar KelimelerYer fıstığı, Radyoaktivite, Gama spektrometresi, HPGe, Yıllık etkin doz Özet: Son zamanlarda birçok ülkede çevresel örneklerdeki (toprak, su, gıda vs.) radyonüklit miktarı hakkında araştırmalar yapılmıştır. Bu çalışmanın amacı, HPGe detektörlü yüksek çözünürlüklü gama spektrometresi kullanılarak Osmaniye ili ve çevresindeki farklı yerlerden toplanan yer fıstığı örneklerinde Karasal;(Ra-226, Th-232 ve K-40) ve antropojenik (Cs-137) radyonüklitlerin aktivite konsantrasyonu ölçmektir. Fıstık örneklerindeki Ra-226, Th-232 ve K-40 aktivite konsantrasyonları(Bq/Kg) sırasıyla, 3.1±1.0'den, 7.6±1.0'e, 3.2±1.0'den 6.6±1.8'e, 256±2.9'den 304.5±7.2'ye arasında değişmektedir. Cs-137 aktivite konsantrasyonu MDA değerinin altında kalmıştır. Investigation of Radiation Activity Growing Peanuts in Osmaniye KeywordsPeanut, Radioactivity, Gama spectrometry, HPGe, Annual effective dose Abstract: In recent years a lot of reviews on radionuclide that environmental samples contained soil, water, nourishment and et al were done in many countries. Aim of this study is to determine the specific activities of important natural and artificial radionuclides such as Ra-226, Th-232, K-40, and Cs-137 peanut that gathered from Osmaniye and various locations around. The specific activities of Ra-226, Th-232, and K-40 ranged from 3.1±1.0 to, 7.6±1.0 Bq/Kg, from 3.2±1.0 to 6.6±1.8 Bq/Kg, from 256±2.9 to 304.5±7.2 Bq/Kg, respectively. The specific activities of Cs-137 were generally remained below detection limits (MDA).
