Can we calculate mean free path aka relaxation length in a particular medium for neutrons from its depth dose profile?

For photons, we know relaxation length or MFP is considered the length it takes to reach 37% of its initial dose or intensity value. Can we apply the same concept for neutrons to calculate their...
