Computers,Radiation, and Ethics

The reduction of the levels of the electromagnetic fields surrounding and emanating from computer screens is discussed in relation to ethical issues of risk reduction, in particular where the factual basis for the actions taken is nonconclusive. The technicaland scientific background is reviewed briefly. Some empirical approaches for determining risks, for example, the method of contingent valuations, are reviewed, and their ethical implications are discussed. When both the risk level and the determination of the certainty of the risk level is unknown, it is not considered responsible to further the work on reduction of the levels of the electromagnetic fields. The present state of knowledge does not seem to warrant further action regarding these fields. It is suggested that the focus of endeavors be directed toward otherconcems, in particular to image quality and the work situation.
