I'd have to look this up.
But I did see a show on Science channel about our magnetic poles. In it there was a discussion on how our poles are getting ready to switch again. When this happens, certain signs occur on the Earth. What they showed was a HOLE in the magnetic lines which is over parts of Australia, Pacific ocean and New Zealand.
This has to do with the core being not completely spherical and hence the magnetic flux lines which protect us from radiation are weak in that area.

I'd have to look around about topical Vit D.
If you want substantial absorption, a transdermal gel is the best carrier. But if you want to block UV? I don't know if it will do so.
Let me look around and see if there is data on its validity.
