 <How long does core stay magnetized without power?

 Years.

 <How many bytes of battery-backed RAM are there in a typical PC?

 Not a lot usually something in the 32-128byte range, maybe more.

 <Haven't there been contemporary memory devices that use nano-scale
 <cores, to eliminate the battery needs and radiation sensitivity of RAM?

 Not that I'm aware of.

Actually, there are a few companys making FRAMs. Essentially they use
a small amount of magnetic material to provide non-volatile storage.
They may even be core shaped :)
