At an energy level, while in the East the Feng Shui sought to optimize communication between humans and their environment, in the West studies began to emerge examining the radiation generated by the Earth, in order to understand the influence of electromagnetic forces on our bodies. Thus the Geobiology (Geo = earth / Bio = life) was born.
In ancient Greece the first treaties on water, earth and wind were developed. They were designed to prevent geo- pathology radiation zones unfavorable for our environmental health.
Referring to environmental health, we found two types of radiation, natural radiation and the one created by man, called artificial radiation.
Natural radiation is emanated by the Earth; its alterations can create variations in the Earth’s electromagnetic field. These variations can be caused by alterations of geophysical origin, geomagnetic networks and environmental radioactivity.
Geophysical disturbances cover groundwater (underwater bags, aquifers, wells or underground leaks), geological faults (underground fractures in the Earth’s layers, produced by the effect of seismic and tectonic forces) and geomagnetic nets (line forces which come from different magnetic directions, responding to a cross pattern of invisible vertical walls that cover the Earth’s surface). They are classified according to the magnetic orientation and the distance apart from each other. The best known geomagnetic networks are the Hartman Lines, Curry Lines and Peyre Lines. There are also other terrestrial events such as telluric chimneys.
Radioactive environmental changes, partly come from the Sun and the Cosmos, but the greater extent received comes from the Earth. This radioactivity arises from the rocks and soil materials, which often contain high concentrations of radon gas. When it emerges to the surface, it alters the health of the person exposed.
