Abstract
A solution for generating ultraviolet diffusive radiation is provided. A diffusive ultraviolet radiation illuminator includes at least one ultraviolet radiation source located within a reflective cavity that includes a plurality of surfaces. At least one of the plurality of surfaces can be configured to diffusively reflect at least 70% of the ultraviolet radiation and at least one of the plurality of surfaces can be configured to transmit at least 30% of the ultraviolet radiation and reflect at least 10% of the ultraviolet radiation.
