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. ***

9215274 Gandhi拟议的研究将适应和扩展有效的计算技术（时域和阻抗方法），以前用于帮助了解射频电磁场对人类的影响，研究工频电磁场。 将使用基于MRI扫描的详细高分辨率、各向异性、基于解剖学的模型，针对实际感兴趣的一系列条件，估计场分布和电流密度。 数值方法的准确性将通过使用缩小比例的人体模型进行实验验证。 这项研究很重要，因为它涉及到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适当的实验条件，用于生物学研究的电力线场对人类的影响，并帮助确定现实的安全准则。 ***
