Abstract

Summary form only given. The shielding effect of a magnetically shielded room (MSR) should be designed for biomagnetism by taking into account the S/N ratio of the biomagnetic signals and the environment magnetic field noise (EMFN), (generated by the movement of automobiles), and for semiconductors by the ratio of the noise level required by the integration of ion beam plots to the EMFN. This paper describes the characteristics and method of predicting the amplitude of the fluctuation of magnetic field (FMF) at any distance and height due to automobile movement.
