Can I run 10/3 NM-B through 1/2 emt? If not, then what size? I am running it to my exterior breaker box. I only need to run it through a six inch piece of conduit. There is already a six inch piece of 1/2 conduit that is not being used. Can I run it through this? If not, then what size?

If your EMT is just used as a sleeve for protection, yes. If the EMT is installed as a raceway (such as installing it between 2 boxes), you'll need to do some calculations based on Chapter 9 in the NEC. My gut feeling is that you'll need a larger size.
