You could ship a Alpha-only source in an envelope if you wanted to, since the paper would stop the radiation. Radium, however, is totally different.....;)

Makes sense... but don't forget that Am-241 is also a gamma emitter.

edit: Just a thought: if you're in the US and shipping anything radioactive without a good reason, you might be labeled a terrorist.

'Alpha-only source';)
I know Am-241 is a gamma emitter, but, IIRC, it is a low level gamma emitter. That means that its emitions are stopped by thinner materials than the high level gamma emitters. That's why its used in detectors.
But if they can't detect any radiation from the box, they can't really say they had enough evidence to open it. See my earlier link for an example.
