Not sure that's a huge worry Ray. There are scores of detection devices all along our borders/sea ports/sea routes further out that can detect emissions from radioactive material. It's certainly a concern I admit, but buoys monitoring container traffic are in place.

You have a lot more faith in that stuff than I do.
I have about as much faith in the folks managing those detection devices as I do in the TSA.
