It is also claimed that groundwater may create radiation caused by the friction of water against mineral deposits,[7] as well as geological faults, due to a claimed difference in the electric charge of the masses on each side of the fault generating radiation.
These are claimed by practitioners to have harmful effects in a phenomenon collectively called geopathic stress.
[9] Practitioners of geobiology will typically use a dowsing rod, pendulum or their hands to ascertain the location of radiation, and then use this information to make an assessment on its effect on a residential dwelling or workplace and upon localised natural life.
Practitioners may also claim be to able to locate and model a building on a basis similar to the theories of Feng shui, Vastu Shastra, or use of Sacred geometry.
[10] The results of techniques used by practitioners of geobiology, such as dowsing or other forms of radiesthesia, have been attributed to the ideomotor phenomenon.
