The conditions of life and the cosmic forces having a biological effect on the human being are influenced by a device for attenuating and regulating the intensity of environmental radiation from buildings, the cosmos or the earth as well as of electromagnetic waves in lived-in areas, especially in the dwellings of individuals. Health damage is avoided by attenuating and regulating the intensity of environmental radiation, in that a layer (1) made of a material which attenuates the permeation of radiation is laid on floors or walls, or is provided so as to be adjustable. <IMAGE>
