Until now, simple shielding is the only way to prevent harmful electromagnetic: wave from TV and monitor. In this study, we adopted special ceramics to Braun tube for radiating FIR ray. In experiment on living organisms, there was some differences between general and ceramics treated Braun tube. The chrysanthemunm the drosophila and the tadpole which were in front of ceramics treated Braun tube showed longer living activity than those in front of general tube. As a result, it is proved that the ceramics treated Braun tube offers good effects to living organisms.
