摘要
由于摄入天然放射性物质的主要来源是食品，本研究旨在评估一些食品中 226 Ra、232 Th 和 40 K 的总承诺剂量。研究人员从开罗的一些市场随机收集了 30 种食品样本，如小麦、豆类、肉类、鸡肉、鱼、摩洛凯、咖啡、茶和奶粉，并用电烤箱烘干。食品样品中 226 Ra、232 Th 和 40 K 浓度的比活度是通过以下方法测量的
Assessment of the Annual Effective Dose due to Intake of Natural Radionuclides from some Food Samples
Since the main source of ingestion exposure to natural radioactivity originating mainly from foodstuffs, the current study aims to assess the total committed doses from 226 Ra, 232 Th and 40 K from some food products. Thirty food samples such as wheat, beans, meat, chicken, fish, Molokai, coffee, tea and powder milk were randomly collected from some markets in Cairo and dried using an electric oven. Specific activity for the 226 Ra, 232 Th and 40 K concentrations in food samples was measured using
