Non-ionizing (or non-ionising) radiation refers to any type of electromagnetic radiation that does not carry enough energy per quantum (photon energy) to ionize atoms or molecules—that is, to completely remove an electron from an atom or molecule. Instead of producing charged ions when passing through matter, non-ionizing electromagnetic radiation has sufficient energy only for excitation, the movement of an electron to a higher energy state. In contrast, ionizing radiation has a higher frequency and shorter wavelength than nonionizing radiation, and can be a serious health hazard; exposure to it can cause burns, radiation sickness, cancer, and genetic damage. Using ionizing radiation requires elaborate radiological protection measures, which in general are not required with nonionizing radiation.
Control of halitosis-generating and other microorganisms in the non-dental upper respiratory tract
ActiveUS20060047329A1Effective controlReduce the burden onElectrotherapyDiagnosticsNon-ionizing radiationTonsil
Disclosed are safe, simple and effective broad-spectrum treatments for halitosis and other microbial infections of the nondental upper respiratory tract useful to treat bacterial and other microorganism species, including anaerobic bacteria. Electromagnetic radiative energy including visible, and optionally, thermal, RF and / or microwave wavelengths, is topically applied to internal surfaces of the upper respiratory tract to destroy or incapacitate superficial microorganisms without the use of antibiotics. One useful apparatus is a handheld energy applicator having a light output head suitable for treating the back of the tongue and the tonsils and which may be interchangeably provided with extensions to reach the sinuses. The energy applicator can be supported and guided by a mounting device held between the subject's teeth, if desired. Useful embodiments of the invention include preparative treatment of the target surfaces with a photosensitizing agent such as an oxidizing agent or a complementary stain. Optionally a pre-treament procedure may be employed to remove detritus and microfloral overgrowths that may mask more deeply resident target microorganisms. Novel treatments include treatment of halitosis by destruction of bacterial species associated with halitosis, such as Atopobium parvulum, by application of non-ionizing radiative energy to the tonsils and the back of the tongue. Another embodiment comprises a candy bar incorporating a halitosis treatment lamp disposed within the candy.

The method comprises illuminating a volume of selected tissue of a mammal with light having wavelengths covering a pre-selected spectral range, detecting light transmitted through, or reflected from, the volume of selected tissue, and obtaining a spectrum of the detected light. The spectrum of detected light is then represented by one or more basis spectral components, an error term, and an associated scalar coefficient for each of the basis spectral components. The associated scalar coefficient is calculated by minimizing the error term. The associated scalar coefficient of the each of the basis spectral components is correlated with a pre-selected property of the selected tissue known to be indicative of susceptibility of the tissue for the pre-selected disease to obtain the susceptibility for the mammal to developing the pre-selected disease.
