Actinic Radiation May 2026

: While primarily associated with the UV range (especially 200–315 nm), it can also include certain wavelengths of visible and infrared light.

: Unlike standard irradiance (which measures radiation on a flat surface), actinic flux is measured as the total radiation received at a point from all directions ( actinic radiation

: It possesses sufficient energy to break chemical bonds, leading to effects like the photo-dissociation of molecules. : While primarily associated with the UV range
