Ultraviolet Light and Health Detection

This research investigates ultra-weak photon emissions in the ultraviolet (UV) spectrum radiated by metabolically active systems in humans, animals, plants, fungi, and bacteria. We are exploring the identification of indicators of health or disease based on the characteristics of ultraviolet radiations from our test subjects.

Using Conventional Equipment to Gather Extraordinary Results

We are using conventional film-based photography as well as a CCD digital lab camera, combined with UV bandpass filters to analyse select wavelengths of the ultraviolet spectrum that are emitted by metabolic processes in our subjects. Ultraviolet light is electromagnetic radiation with a wavelength 10nm to 400nm, shorter than visible light (400nm – 700nm). All living cells of bacteria, plants, animals, and humans emit ultraviolet radiations as a result of the chemical reactions involved in cellular reproduction, metabolism, and especially stress reactions. Our goal is the accurate analysis of these emissions leading to more accurate, and less invasive, assessments of health.

Building Upon Research Precedent

Since the early 20th century, numerous researchers have noted that, similar to phosphorescence, living organisms emit a range of detectable energies. In the 1920s, Russian embryologist Alexander Gurwitsch determined that an unknown form of radiation from an onion root tip appeared to pass through a UV-transparent quartz glass barrier, causing increased mitosis in an adjacent onion root. He named this "mitogenetic rays" because his experiments suggested to him that they had a stimulating effect on cell division, mitogenesis, and this effect was transmitted across a measured gap. Later, Gurwitsch utilized a very basic galvanometer to detect electromagnetic radiation in the UV spectrum from his subjects. His mitogenic theory seems to have been born out - in the 1940's, researchers determined that shorter wave UV radiation did in fact stimulate cellular mitosis, cell division, and even DNA damage.

Since then a broad range of research around ultraweak emissions has continued. Several factors greatly enhanced the depth of this research – the advent of the photomultiplier tube, as well as the emergence and refinement of the electron microscope, as well as CCD and CMOS camera systems. From the 1960’s to present a great deal of evidence has emerged showing conclusively that all biological systems emit detectable radiations, that the environment and available nutrients effect that radiation, and that when biological systems are disturbed they clearly respond with a reduction or variation of radiation output.

Our research is motivated by the present need for affordable, as well as non-invasive, modes of health assessment. Current medical analysis systems can be prohibitively costly (MRI/CAT scanning technology) and may have negative impacts (radiation, marker dye injections). The development of a cost effective, portable, easily utilized, and non-intrusive medical assessment technology is badly needed.
