Abstract

This invention relates to a method, process and apparatus for disinfecting and sterilizing all types of surfaces contaminated with microorganisms and toxic substances to render both inactive. Furthermore, this invention relates to both a method and apparatus for disinfecting and/or sterilizing breathable air and then using this air to protect a confined space from external contamination. The apparatus consists of a new ultra-violet (NUV) source that is more effective than mercury based 254 nm light for destroying DNA of virus, bacteria, spores and cists. It is most effective in breaking chemical bonds in toxic gases and Biotoxins that are useful to terrorists. It is combined with other apparatus that remove particulates and byproducts sometimes produced by the NUV source and maintains positive pressure of the confined space so as to prevent the influx of air from outside the protected zone.

Claims (21)

1. A process for destroying a DNA or RNA of a microorganism on a substance or on a surface comprising the steps of:

generating photons of a wavelength corresponding to a peak absorption wavelength of proteins, or DNA, or RNA, the wavelength being 222 nm;

directing the photons to a substance or surface to be disinfected, whereby the photons are generated to destroy a plurality of chemical bonds within the proteins, DNA, or RNA of the microorganism; and

wherein the substance or surface to be disinfected is human or animal tissue.

2. The process of claim 1 wherein the human or animal tissue is one of blood, an organ, or a wound.

3. The process of claim 1 wherein the microorganism is at least one of a bacteria, a virus, a fungus, an amoeba, and a protozoa.

4. The process of claim 1 wherein the step of directing is performed for approximately two seconds.

5. The process of claim 1 wherein the step of generating photons comprises activating a lamp positioned within a wand, and wherein the step of directing comprises positioning of the wand.

6. The process of claim 1 wherein the step of directing comprises passing the generated photons through a fiber optic cable.

7. The process of claim 1 wherein the step of generating photons comprises activating a lamp.

8. The process of claim 7 wherein the lamp comprises a cover, the cover transparent to 222 nm.

9. The process of claim 1 wherein the step of directing the photons further comprises a step of providing 540 kJ/mole of photon energy to the substance or surface to be disinfected.

10. The process of claim 1 wherein the step of directing the photons further comprises providing a radiant dose energy of 40 mJ/cm 2 to the substance or surface to be disinfected.

11. The process of claim 1 wherein the step of directing the photons further comprises providing a radiant dose energy of 60 mJ/cm 2 to the substance or surface to be disinfected.

12. The process of claim 1 wherein the human or animal tissue is skin.

13. The process of claim 1 wherein the human or animal tissue is human tissue.

14. The process of claim 1 wherein the human or animal tissue is human skin.

15. The process of claim 1 wherein the human or animal tissue is tissue of a living animal.

16. The process of claim 1 wherein the human or animal tissue is tissue of a living human.

17. The process of claim 1 wherein the human or animal tissue is skin of a living human.

18. The process of claim 1 wherein the human or animal tissue is skin of a living animal.
