Of course you'd want it to be something like a light year thick. That may be impractical. Plus there are minor structural problems, such as how to stop it from spontaneously collapsing into a black hole.
As I recall from school, your lead suit would need to be more than 3 lightyears thick to make the chance of a neutrino (that was already heading towards you) going through you fall to 50%.

A lead suit helps.

When I said helps, I didn't say by how much...
Your comment makes me want to re-read the hitchhiker's guide.
