Abstract

The present study investigates gross alpha (GA) radioactivity levels in hazelnut kernels purchased from markets in Türkiye. 10 different hazelnut samples were crushed and made ready for counting. The alpha counts were obtained via ELSEC 7286 low level alpha counter with ZnS scintillator and EMI 6097B photomultiplier tube. The samples were placed in front of the detector to acquire the counts. All samples were counted isochronously. In addition to the GA activity measurement, total annual effective dose (AED) value for different age groups owing to ingestion was calculated for each sample. It was observed that the GA radioactivity levels in the samples were quite low, and total AED values were considerably lower than the WHO worldwide average AED value (290 μSv/year).
榛子核仁中总α放射性水平的测量和年有效剂量的估算
本研究调查了从土耳其市场上购买的榛子核仁中的总α(GA)放射性水平。10 个不同的榛子样本被粉碎并准备进行计数。α计数是通过配有 ZnS 闪烁器和 EMI 6097B 光电倍增管的 ELSEC 7286 低浓度α计数器获得的。将样品放在探测器前进行计数。所有样品都是等时计数。除了测量γ-氨基甲酸乙酯的放射性活度外,还计算了每个样本在不同年 龄组别摄入γ-氨基甲酸乙酯后每年的总有效剂量值。结果显示,样本的γ-基因活度水平相当低,而总有效剂量值则大大低于世界卫生组织的全球平均有效剂量值(290 微希/年)。
