摘要

本研究调查了科亚地区市场菜篮子中各种食品样本(包括国产和进口产品)中天然放射性核素的放射性活度浓度。通过使用高纯锗(HPGe)探测器,样本涵盖了一年生作物(如咖啡、茶、芸豆)、树坚果(如杏仁、开心果)和其他产品(如牛肉、鱼、牛奶)。这项研究通过提供放射性核素浓度的基线数据和评估潜在的健康风险,填补了一个显著的空白。²²⁶Ra、²³²Th 和 ⁴⁰K 的平均放射性活度浓度分别为 0.943、0.367 和 191.8 Bq kg-1。镭当量活度值介于 2.88-58.48 Bq kg-1 之间,均低于安全限值。平均终生超额癌症风险(ELCR)为 0.154 mSv a-1,表明大多数样本都是安全的,但咖啡和茶的含量较高。这项研究提供了对未来研究和监管监测至关重要的新数据,强调了进一步调查地质对放射性核素水平影响的必要性。

Estimation of radiological health risks due to 226Ra, 232Th, and 40K in foods consumed in Iraqi Kurdistan Region.

This study investigates the activity concentration of natural radionuclides in a diverse range of food samples in the Koya district markets food baskets, including both domestic and imported products. The samples cover annual crops (e.g. coffee, tea, kidney beans), tree nuts (e.g. almonds, pistachios), and other items (e.g. beef, fish, milk) by using a high-purity germanium (HPGe) detector. This research addresses a notable gap by providing baseline data on radionuclide concentrations and assessing potential health risks. Average activity concentrations for ²²⁶Ra, ²³²Th, and ⁴⁰K were 0.943, 0.367, and 191.8 Bq kg-1, respectively. Radium equivalent activity values ranged from 2.88-58.48 Bq kg-1, all below the safety limit. The average excess lifetime cancer risk (ELCR) was 0.154 mSv a-1, indicating safety for most samples, though coffee and tea showed higher levels. This study provides new data crucial for future research and regulatory monitoring, underscoring the need for further investigation into geological impacts on radionuclide levels.

期刊介绍: Isotopes in Environmental and Health Studies provides a unique platform for stable isotope studies in geological and life sciences, with emphasis on ecology. The international journal publishes original research papers, review articles, short communications, and book reviews relating to the following topics: -variations in natural isotope abundance (isotope ecology, isotope biochemistry, isotope hydrology, isotope geology) -stable isotope tracer techniques to follow the fate of certain substances in soil, water, plants, animals and in the human body -isotope effects and tracer theory linked with mathematical modelling -isotope measurement methods and equipment with respect to environmental and health research -diagnostic stable isotope application in medicine and in health studies -environmental sources of ionizing radiation and its effects on all living matter
