9215274甘地拟议的研究将使以前用来帮助理解射频电磁场对人体影响的有效计算技术(时域和阻抗方法)适应并扩展到工频电动势的研究。将使用基于核磁共振扫描的详细的高分辨率、各向异性、基于解剖学的模型，针对一系列实际感兴趣的条件，估计场分布和电流密度。数值方法的准确性将用缩小比例的人体模型进行实验验证。这项研究之所以重要，是因为它涉及一个当前公众关注的问题。从这项研究中获得的信息可以帮助确定合适的实验条件，用于电力线电场对人类影响的生物学研究，并有助于确定现实的安全指南。***

9215274 Gandhi The proposed research would adapt and expand on efficient computational techniques (both time domain and impedance methods), previously used to help understand radio-frequency EM field effects on humans, to the study of power-frequency EMF's. Field distributions and current densities will be estimated, using detailed high resolution, anisotropic, anatomically-based models based on MRI scans, for a range of conditions of practical interest. The accuracy of the numerical methods will be verified experimentally using a reduced scale models of the human. This research is important because it deals with an issue that is of current public concern. The information gained from this study could help determine appropriate experimental conditions to use in biological studies on the effects of power-line fields on humans and to help determine realistic safety guidelines. ***
