Flow chart showing the stages used by RADDOSE to calculate the dose absorbed by a crystal. The steps involved in the fluorescence escape corrections are coloured blue. Initially the contribution of a given element to the absorption coefficient is computed (F). The unit-cell size and contents of the crystal influence this term. If the absorption edge for an element can be reached by the incident beam energy, the relevant photoelectric cross sections [obtained from the mucal library (McMaster et al., 1969BB26)] can be used along with the probabilities of ionization, fluorescence yield, crystal thickness and absorption coefficient at the fluorescence energy to calculate the probability of fluorescent escape for this element.
