Claims
- 1. A method of sterilizing an area using ultraviolet radiation, comprising the steps of.
(a) causing ultraviolet-C radiation to be emitted from multiple positions within an enclosed area; (b) measuring a reflection of ultraviolet-C radiation from the multiple positions within said enclosed area; (c) calculating the ultraviolet-C radiation level necessary to sterilize said enclosed area and comparing it with the measured reflected ultraviolet-C radiation; and (d) terminating the emission of ultraviolet-C radiation after determining that the required minimum ultraviolet-C radiation has been reflected from the multiple positions within said enclosed area.
- 2. A method of sterilizing an area using ultraviolet radiation as described in claim 1,
wherein motion within said room is detected prior to the initiation of emission of ultraviolet-C radiation.
- 3. A device for sterilizing an area using ultraviolet radiation, comprising:
(a) a base; (b) a plurality of ultraviolet-C radiation emitters, wherein said plurality of ultraviolet-C radiation emitters are located in at least two places within an enclosed area to be treated, with each of two places remote from each other, and wherein said ultraviolet-C radiation emitters are directed towards an enclosed area to be treated; and (c) at least one radiation receiver which receives reflected ultraviolet-C radiation, wherein said receiver measures said reflected ultraviolet-C radiation.
- 4. A device for sterilizing an area using ultraviolet radiation as described in claim 3, further comprising a motion detector which communicates with said plurality of ultraviolet-C radiation emitters.
