Abstract
The concept of risk communication is becoming very common in Japan. The concept has been applied to various fields, for instance, chemical engineering industries, nuclear industries, medical radiation exposure to patients, and transmission lines EMF exposure to the public. In this paper, some difficulties in making a risk communication with the members of public are introduced in these fields. The most troublesome is that resident people is totally indifferent to relevant risk to chemicals and nuclear in normal operation. As another difficulties, it turned out that patients are very concerned about medical radiation risk after finding no problems in health using diagnostic radiation and many electric engineers on site are hard to educate as EMF risk communicators.
