A C-Band Disinfector disinfects objects placed within the device by subjecting the objects to closed-loop emissions of UV-C radiation. UV-C sensors measure reflected UV-C radiation and control the period of operation of the device. In an additional embodiment, UV-C radiation is transmitted by fiber-optic cable to a particular area of an object to be disinfected. After the prescribed dose is applied, the fiber-optic cable is moved to a new area of the object, and the UV-C disinfection process continues until all areas of the object have been disinfected by exposure to the prescribed dose of the UV-C radiation.
