Topflight British government boffins say they have at last cracked the knotty problem of cleanup following Alexander Litvinenko style radioactive-poison murders or similar incidents in which radiological contaminants are spread about the place.

Fine, but....

Fine, but even a tonic water lover like me doesn't consume it all the time.

The knowledgeable out there please advise us all (we need to know in case we visit Russia anytime soon).

Europol

And because the Russian federation is a member of europol if you get arrested demonstrating against Litvinenko's murder the police hand them a copy of your record and DNA etc.

Nice to have friends like that.

When they say the long range version would be "non portable"

Do they mean like the Hale telescope is "non portable"?
