radon in limestone

["Tom Savin" <lexicon@hotbot.com>]

Greetings radsafers:

An interesting question came up in a recent conversation - it was speculated that limestone (480 million years old (Ordivician age) could be a source of radon.  I tended to disagree because I think that it had plenty of time to escape while it was sedimented underwater.  Does anyone know anything about this or can recommend a reference.  Thanks 

                                Tom
