Use diffusion theory to estimate sonoluminescence light transmission in biological tissues. A unit-power isotropic point source is buried in an infinite turbid medium. Assume that the absorption coefficient is 0:1 cm-1, the scattering coefficient of a 5-cm thick tissue is 100 cm-1, and the scattering anisotropy is 0.9. Calculate the light fluence rate integrated over a sphere of a 5-cm radius centered at the source.
