Geiger Counter: Science oriented investigators use Geiger counters to measure anomalous readings of low-level (non-harmful) radiation thought to be one of the energies emitted by a manifesting entity. Any levels of radiation detected, whether or not they coincide with alleged paranormal activity, are recorded and published with other environmental data in the client's Investigation Report. As with changes frequently noted in other environmental conditions, no definitive evidence as yet has been acknowledged by the scientific community that draws a reliable correlation between radiation readings and paranormal activity, nor that there exists such a thing as "paranormal" energy; it is merely a working hypothesis at present.
