optical dosimetry has been investigated in a tissue phantom, consisting of an aqueous suspension of uniform polystyrene spheres plus methylene blue as a chromophore. the rate of light absorption by the dye was measured for different concentrations of dye and scatterers, using the photosensitized inactivation of an enzyme as a sensitive internal actinometer. the optical penetration depth of each sample was measured with a fiber optic probe technique. the results are in good agreement with the predictions of the diffusion model, and the high scattering limit of kubelka-munk theory
