A system providing effective, broad spectrum UV-C or other ionizing radiation clinical surface disinfection, high intensity UV-C light emitting diodes (LEDs) of incrementally differing wavelengths are sequentially embedded in densely packed reflective nacels (cups or pockets) forming the surface of a rotating spherical or hemispherical structure. A combination of UV-C emitter component location and activation with the rotational and reciprocal elevation functions of such structures produces complete and continuous environmental overlapping UV-C energy scattering.
