There are many electromagnetic sources in medical environment. Not only electromagnetic compatibility (EMC) problems but also safety of human exposure to electromagnetic fields (EMF) is an important issue. Especially occupational exposure to extensive high EMF of MRI operators has become large concern because of very high intensity of EMF around MRI systems. There were many discussions on MRI operators during introducing EU Directive on occupation EMF exposure. In this presentation, the rationale of the international guidelines for human exposure to EMF, which issued by International Commission on Non-Ionizing Radiation Protection (ICNIRP), are introduced and recent activities on research and legislation on EMF safety are summarized.
