Mat for protection against earth radiation - has natural cork with coating of quartz sand

摘要

A cork mat is suggested as a protection against radiation from the earth. The natural cork plates should be at least 4mm thick and their underside is covered with a layer of quartz sand. Furthermore, the mats are enclosed in a linen cloth for protection during transport and better wear and durability. The mats may be of various sizes e.g. 1.80m x 0.09m would be suitable for a bed, smaller sizes could be used under chairs or desks etc.
