The system is comprised of a UV light assembly that can be integrated into the manufacturing stage of a specific item, or installed on existing items as an aftermarket product. The system also includes a power source, such as direct wiring, a battery, or solar panels; one or more UVC bulbs; a safety contact switch to deactivate the UVC bulb or bulbs; and a timer to conserve power and bulb longevity. ## Claims ### Claim 1 An ultraviolet radiation sterilization system comprising: at least one bulb; an internal power source; a switch; a timer and a controller; and wherein said ultraviolet radiation sterilization system may be affixed to a substrate. ### Claim 2 (depends on 1) The sterilization system of claim 1, wherein said system is portable. ### Claim 3 (depends on 1) The sterilization system of claim 1, wherein said power source is a battery. ### Claim 4 (depends on 3) The sterilization system of claim 3, wherein said battery is rechargeable. ### Claim 5 (depends on 1) The sterilization system of claim 1, wherein said at least one bulb is a UV-C bulb. ### Claim 6 An ultraviolet radiation system for a container comprising: a container having a door capable of being opened, an insert, a front edge, a left wall, a right wall and an interior chamber; at least one UV light source attached to either said right or left wall; a power source; and a switch that is automatically releasable. ### Claim 7 (depends on 6) The ultraviolet radiation system of claim 6 further comprising at least one sensor. ### Claim 8 (depends on 7) The ultraviolet radiation system of claim 7, wherein said at least one sensor is a pressure sensor. ### Claim 9 (depends on 6) The ultraviolet radiation system of claim 6 furtherer comprising a controller and a timer. ### Claim 10 (depends on 9) The ultraviolet radiation system of claim 9, wherein the switch energizes the timer when the door is opened, which allows the power source to illuminate the UV light source. ### Claim 11 (depends on 6) The ultraviolet radiation system of claim 6 further comprising a warning indicator and a safety indicator. ### Claim 12 (depends on 6) The ultraviolet radiation system of claim 6, wherein said power source is one of a direct wiring, a battery or a solar panel. ### Claim 13 (depends on 6) The ultraviolet radiation system of claim 6, wherein said ultraviolet radiation system is affixed to an outer surface of said container. ### Claim 14 (depends on 6) A method of operating the ultraviolet radiation system of claim 6 comprising: opening said container; releasing automatically said switch; deactivating said UV light source; and closing said container and activating said ultraviolet radiation system. ### Claim 15 An ultraviolet radiation sterilization system for use with a drawer having an interior chamber wherein ultraviolet radiation occurs, wherein the ultraviolet radiation sterilization system comprises: at least one UV-C bulb or tube; a plurality of sensors to detect if said drawer is in an open position or a closed position, wherein ultraviolet illumination only occurs when said drawer is in the closed position; and a power wire leading to a power supply. ### Claim 16 (depends on 15) The ultraviolet radiation sterilization system of claim 15, wherein said drawer is a cash drawer. ### Claim 17 (depends on 15) The ultraviolet radiation sterilization system of claim 15, wherein at least one of said plurality of sensors is a motion sensor. ### Claim 18 (depends on 15) The ultraviolet radiation sterilization system of claim 15, wherein at least one of said plurality of sensors is a pressure sensor. ### Claim 19 (depends on 15) The ultraviolet radiation sterilization system of claim 15 further comprising a timer. ### Claim 20 (depends on 15) The ultraviolet radiation sterilization system of claim 15 further comprising a warning indicator and a safety indicator.
