I would not take or do ANYTHING before a rad treatment. There are many things that can serve in a bolus capacity and increase the intensity and effect of the radiation, causing more localized damage than it would otherwise.

I was also told not to put anything on my skin prior to treatments. I would think swallowing any kind of oil would have the same effect.
