A few years ago, I heard about a very penetrating scanner for shipping containers, that used muons, which are second-generation particles, analogous to charm, but for leptons. I don’t know whether it’s still promising or not.
I don’t know of any other applications for second- or third-generation particles. They all have so much shorter lifetimes than muons, it’s hard to do anything with them.

The muon-based scanner is still alive—it was mentioned in a recent APS news. Apparently, it relies on cosmic ray muons only.
