: It possesses sufficient energy to break chemical bonds, leading to effects like the photo-dissociation of molecules.
: While primarily associated with the UV range (especially 200–315 nm), it can also include certain wavelengths of visible and infrared light. actinic radiation
: 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 ( : It possesses sufficient energy to break chemical
steradians). This is essential for calculating the rate at which molecules in the atmosphere break apart (photolysis). Common Applications and Effects actinic radiation
