Radionics

Some people claim to have the paranormal or parapsychological ability to detect "radiation" within the human body, which they call radiesthesia. According to the theory, all human bodies give off unique or characteristic "radiations" as do all other physical bodies or objects. Such radiations are often termed an "aura". Radiesthesia is cited as the explanation of such phenomena as dowsing by rods and pendulums in order to locate buried substances, diagnose illnesses, and the like. Radiesthesia has been described as a mixture of occultism and pseudoscience by critics.
