Medical Physics Question about the formula D(x)=alfa*mu*I(x)/rho

Main Question or Discussion Point

Hello I had two doubts, I know that medical physicist when working with x-rays use the formula D(x)=alfa*mu*I(x)/rho
where D(x) is the dosis absorbed
Alfa is the factor of the energy that damages
Rho is the density
mu is the absorbtion coefficient
My doubt is the following: Does this formula work for all interactions? (compton, fotoelectric efect, pair production and coherent scattering)
Another doubt, does photodisintegration occurs when working with x rays?
where can I find information on the topic? Thanks a lot

I believe they used a human body cut into 1cm cubes to get original X-ray density data.

could be a myth.
