Determine and plot the ratios μtr/μ and μab/μ from 5 keV to 100 MeV for
(a) air,
(b) water,
(c) muscle,
(d) bone, and
(d) lead.
Use the excel data file and use logarithmic scales for the energy (x-) axes. Make five plots corresponding to the five substances and on each plot put the graphs of μtr/μ, and μab/μ.
