optics - Mean free path of UV photon


I was wondering if there's a simple way to compute the mean free path of UV photons in a optically thick medium with density n.


I've looked up at the literature and found out that the mean free path of Lyman-Werner band photon is ~1 Mpc on cosmological scales but 0.1 pc inside clouds. However, I would like to read an article about that but I can't find any.
