isotopes? I'm moving some radioactive isotopes, mostly cobalt, with me for research purposes. I'm planning on traveling by air and was wondering what I should do to insure my materials don't cause a security panic. I don't plan on checking my bag and the samples themselves are rather small, around 5g in some cases. Is there someone I need to contact ahead of time or should I just show up very early and expect to be screened.
