Abstract

We investigated the biological effects of the magnetic field produced in the superconducting Maglev system environment, such as the extremely low frequency intermittent pulsed magnetic field (LFIP-MF) that is generated along the guideway when a Maglev train passes. We observed no evidence of any biological effects from exposure to the Maglev system's LFIP-MF in "in vivo" long-term exposure experiments using AKR/JSea mice, in "in vitro" short-term exposure experiments as bacterial mutation assay, a yeast mutation assay or an analysis of global gene expression profiles in yeast. These results suggest that the Maglev system's environmental LFIP-MF does not have any health/biological effects that would need to be considered as part of an environmental assessment.
