PMMA (Perspex, Acrylic, Plexiglass)
(must be between 3 and 400)
(Energy must be set to 0 to use the wavelength)
The data used in this script were obtained from

Since the absorption is calculated by interpolation, results around an absorption edge may not be correct.
Note that absorption may not be proportional to the energy transfered to the material. This means flourescence or dose may not be proportional to absorption.
