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 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.

La présente invention concerne un procédé, un traitement et un appareil pour la désinfection et la stérilisation de tous types de surfaces contaminées par des micro-organismes et des substances toxiques pour les rendre inactifs. L'invention concerne également un procédé et un appareil pour la désinfection et/ou la stérilisation de l'air respirable suivie de l'utilisation de cet air pour protéger un espace confiné contre une contamination externe. L'appareil est constitué d'une nouvelle source de lumière ultraviolette qui est plus efficace qu'une lumière de 254 nm à base de mercure pour la destruction d'ADN de virus, de bactéries, de spores et de cistes. Il est plus efficace pour la rupture de liaisons chimiques dans des gaz toxiques qu'utilisent les terroristes. Il se combine avec d'autres dispositifs qui éliminent des matières particulaires et des sous-produits générés parfois par la nouvelle source de lumière ultraviolette et maintient une pression positive de l'espace confiné afin d'empêcher la pénétration d'air de l'extérieur de la zone protégée.
