A radiation system includes a radiation device coupled to a control unit; a radiation blocker having an adaptor opening for receiving the radiation device when the radiation device is positioned on the radiation blocker; and a carrier comprising a first compartment for housing the radiation blocker and, a second compartment for housing the control unit. The adaptor opening can dimensionally fit the radiation device to block radiations from the radiation device when the radiation device is positioned in the radiation blocker. The radiation device can produce radiation having peak radiation wavelength in a range of from about 250 nm to about 450 nm and can have a peak irradiation power in a range of from about 0.5 W/cm2 to about 10 W/cm2.
