How about granite and gneiss? Might explain why we are a little mad (Highlanders)? Ha!

Like the old Readybreck ads. Always thought these were inspired by concerns about caesium in milk. |

Not that far, Wullie! |

As another example, potassium 40 has a half life of 1.5 billion years, and there is enough in bananas to make them measurably radioactive.
Now, I'm not keen on bananas when they're a bit 'green', Dave - but I'm fairly sure they'd be over-ripe by then.....   |

Entomb Nigel F****e in the stuff. Encased in glass blocks Blocks buried deep in lead containers should suffice for a few thousand years.
Between you both, you're coming up with some good ideas for that insufferable ****.  |

Kate, have a look at the half life of Plutonium 240, we are looking at 1,000,000,000,000+ years or 475,000,000,000 years for Pu 238. I’m not sure “a few thousand years” is going to solve the problem. Dumping the whole lot into the sun might be a solution. A fine plan until the launch vehicle blows up in the atmosphere!!
Mick
PS Wiki says the half life of Pu240 is a little under 7000 years not the above!
My apologies for that, for some reason the App I use for the periodic table gives two sets of data for each isotope of Plutonium, for each isotope one is reasonable and the other somewhat exaggerated. Further reading suggests that the very long half lives are for spontaneous fission. Just as well I’m not a nuclear physicist. The App doesn’t specify the decay type, I got the information from the Royal Society of Chemistry web site. |
