US-Egypt Cooperative Research: Health Hazards due to Radiation from Mobile Base Stations

无线通信和应用的快速增长使得大量移动基站的建设和持续维护成为必要。这些站发出的辐射模式在空间上是不同的，可以通过吸收辐射对人体造成严重的健康危害。全球标准安全限制是由特定的吸收率决定的，旨在调节天线辐射与人体的相互作用。基站发射的射频/微波比手持设备强几个数量级，对住在这些基站附近的人构成潜在的健康风险，安装和维护这些基站的人也可能面临风险。本提案的主要目标是开发一个用户友好的软件模拟环境，以准确和快速地计算基站辐射对健康的影响。拟议的工作将采用一种模拟软件包，而不是使用人体受试者并直接测量辐射，该软件包将快速有效地模拟来自移动基站的辐射场，并利用该信息计算人体的特定吸收率。为了实现这些目标，PI将与埃及吉萨电子研究所的Hala Abdel Monem Elsadek博士和Hesham Ezzat Salem Eldeeb博士合作。这些研究人员之前的合作产生了一个模拟包和一个并行处理方案，它将使复杂的计算和建模能够模拟对健康的影响，并且通过托管该研究所网站的这个环境，该项目将使其他研究人员能够使用和收集模拟的辐射影响数据。知识价值。从技术、社会、经济和法律的角度来看，电磁辐射的生物效应是一个重要而具有挑战性的问题。这项工作采用了一种创新的方法，使用数值技术来模拟基站发射的辐射场，并在不使用人类受试者的情况下计算辐射吸收率。将模拟包与并行处理方案相结合，将允许这些计算准确而快速地进行。更广泛的影响。这项提议的工作建立在美国和埃及科学家几年来关于数值模拟技术和并行计算方案发展的讨论和研究的基础上。该项目将提供机会进一步开展这种合作，并为这些技术和计划开发新的应用，这些技术和计划可能有效地提高移动基站的安全性并减少对人类健康的风险。该项目将为美国青年科学家和学生提供科学和文化交流的机会。在埃及方面的支持下，早期的埃及科学家和学生将在加州大学欧文分校接受培训。该项目由美国-埃及联合基金项目资助，该项目向两国的科学家和工程师提供赠款，以开展合作研究。

Rapid growth of wireless communications and applications has necessitated the construction and ongoing maintenance of a large number of mobile base stations. These stations emit a radiation pattern that varies spatially and can pose a serious health hazard to the human body through radiation absorption. Global standard safety limits, which are determined by specific absorption rates, are set to regulate the interaction of antenna radiation with the human body. RF/microwaves emitted from the base stations are several orders of magnitude greater than handheld devices and pose potential health risks to people who live near these stations and those who install and maintain these stations can potentially be at risk. The main objective of this proposal is to develop a user friendly software simulation environment that will accurately and quickly calculate the health effects of base station radiation. Rather than using human subjects and measuring the radiation directly, the proposed work will employ a simulation package that will quickly and efficiently simulate the radiation field from a mobile base station and use that information to calculate specific absorption rates for a human body. To achieve these goals, the PI will collaborate with Dr. Hala Abdel Monem Elsadek and Dr. Hesham Ezzat Salem Eldeeb from the Electronics Research Institute, Giza, Egypt. Prior collaboration between these researchers yielded a simulation package and a parallel processing scheme that will enable the complex calculations and modeling to simulate the health effects and by hosting this environment of the institute's websites the project will enable other researchers to use and collect simulated radiation effects data. .Intellectual Merit. The biological effects of electromagnetic radiations present an important and challenging problem from technical, social, economical and legal points of view. This work employs an innovative approach to use numerical techniques to simulate the radiation field emitted from a base station and to calculate the radiation absorption rates without using human subjects. Coupling a simulation package with parallel processing schemes will allow these calculations to be made accurately and quickly.Broader Impacts. The proposed work builds on several years of discussions and research between US and Egyptian scientists on the development of numerical modeling techniques and parallel computing schemes. This project will provide the opportunity to further this collaboration and to develop new applications for these techniques and scheme that may be effective in improving safety of mobile base stations and reduce the risk to human health. For US junior scientists and students, this project will provide opportunities for scientific and cultural exchange. Early career Egyptian scientists and students will be trained at the University of California-Irvine with support from the Egyptian side.The project is funded under the US-Egypt Joint Fund Program, which provides grants to scientists and engineers in both countries to undertake cooperative research.
