Not sure if I suck at math... (And I posted this on the site before I saw slashdot picked up the story)
Plutonium has a half life of 24,000 years. If it started COMPLETELY PURE, it would only be 99.8% pure at the end of 70 years.

For the (more) paranoid, look up "Shamirs Secret Sharing Scheme." (apt-get install ssss)
It allows you to split up a "secret" into a number of "shadows." Then, only when X people get together, they can recover the secret. I've always meant to implement this where you can use ssss to split up a private key, then you can keep an-to-date list of certain passwords and email it out to them periodically. The burden isn't on them everytime you want to change a password, the private key will open the new file.
I'd like to pretty this up as a web app so people can handle this stuff automatically. The super-paranoid version is you can have 1 of the "shadows" only get released on a deadmans switch...
