Could give some more specific details at the beginning, such as for exposure time (could make it an even year), could also state that it is tungsten we're dealing with if it is the properties for tungsten, but I guess it's not hugely important for this task
Could also state before the dt/settings box that the simulation will continue for 3 half-lives after exposure
For the axis labels on the figures, could use parenthesis instead of square brackets?
The time in the final figure could be shown in terms of years rather than seconds, might be easier to put in perspective
Closes #60
