Compare the number densities of each nuclide between the ALARA and OpenMC activation problems.
One approach is to plot the ratio as a function of the nuclide ID.
Another approach is to plot the ratio as a function of the number density (chose one result as a reference). This will allow us to be less concerned about differences where the number density is very low.
