Anti-radiation features of the volcanic rocks

As the developments of the technologies, the electromagnetic radiation as a new pollution has becomes increasingly concerned. The human bodies are good conductors, and the electromagnetic radiations can be harmful to the human body. Generally, the radars, television and broadcast launching systems, RF inductions, micro-wave medical equipments, kinds of edm plants equipments, communications transmitting stations, satellite communications sites, large Power stations, power transmission and transformation equipments, metros and electric trains, and most of the appliances can produce kinds of the radiations.

The natural volcanic rocks have the strong abilities to absorb the harmful substances in the air, such as the formaldehydes, radiations, and the dusts in the air, as they are suitable for the growth of the zoogloea.
