Re: [nafex] fertilzing

To my understanding - and I'm not a nuclear physicist, and don't play one
on TV - is that radon, out in the open, is not a concern. It's a potential
problem when it's seeping into and accumulating in closed spaces
(basements,etc.). I suspect that in an open-field setting, any radon (it
is a gas) that might be present/released would quickly dissipate to
nothingness.
