Consider licensing magnetic resonance imaging (MRI) units having field strengths exceeding 2 t, in order to ensure that protective measures are implemented.
考虑对磁场强度超过2t的磁振造影(MRI)器械许可证的颁发，以便确保实施防护措施。

Magnetic storms also heat the upper atmosphere, changing its density and composition and disrupting radio communications and GPS units.
磁暴还会对高层大气存在加热作用，改变其密度计组成，中断无线电通信与GPS装置。
