摘要

The purpose of this paper is to assess electromagnetic environment of nuclear magnetic resonance (NMR) device in hospital, in considering of the proposed construction of subway lines which would pass the hospital. A method is proposed to quantitatively analyze and evaluate electromagnetic interference of NMR device. It is derived through the analysis and evaluation: when subway line passes through the hospital, the field strength surrounding the hospital can reach 30dBuT to 40dBuT at several frequencies, which is greater than 20dBuT-the threshold of the NMR device. It can ensure the NMR equipment working normally, after applying an electromagnetic shielding measure which makes sure that the electromagnetic shielding effectiveness reaches 80dB.
