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
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

This paper presents an additional approach in the field of polynomial bases, utilizing generalized complex conformable fractional derivative and integral operators. These operators are applied to polynomial bases of complex conformable derivatives (GCCDB) and generalized complex conformable integrals (GCCIB) in Fréchet spaces. We also investigate their convergence properties within closed disks, open disks, open regions surrounding closed disks, origin and for all entire functions, employing the Cannon sum, order, type and -property as convergence criteria for our study. The significance of this work lies in generalizing

A vital device for administering radiotherapy, especially intensity-modulated radiation treatment (IMRT) is the Central Opening Carbon-Fiber Couch. There doesn't seem to be any evidence in the literature about the impact of the thickest section (edge couch) on the dose distribution, even though multiple tests were conducted with the radiation field incident on the center of the couch. In this study, we evaluated and improved the computed beam profile doses for the under-couch fields for various field sizes for energy 6MV to reduce the skin surface dosage
