Where I is intensity after attenuation, I o is incident intensity, μ is the linear attenuation coefficient (cm-1), and the physical thickness of the absorber (cm).. Dependence of gamma radiation intensity on absorber thickness NettetThe specific (radiative) intensity is a radiometric concept. Related to it is the intensity in terms of the photon distribution function,[5][24]which uses the metaphor[25]of a particleof light that traces the path of a ray. The idea common to the photon and the radiometric concepts is that the energy travels along rays.

"In physics, the intensity or flux of radiant energy is the power transferred per unit area, where the area is measured on the plane perpendicular to the direction of propagation of the energy. In the SI system, it has units watts per square metre (W/m ), or kg⋅s in base units. Intensity is used most frequently with waves such as acoustic waves (sound) or electromagnetic waves such as light or radio waves, in which case the average power transfer over one period of the wave is used.
