Hey Radsafe,
     Good Memory.  There was a gamma forest  experiment at Brookhaven.  
They showed us the
forest during the 1980 Summer Health Physics Training Program there.   By 
then, the source was
gone.  But you could see the former effects on tree growth of the  source 
going radially outward from
the original source position.  Trees close in were shorter.  It  was pretty

I don't know about a reactor, but there was a  Cs-137 source used to study
this effect at Brookhaven, I think.  I  think that this also turned into a
study case in the production of  skyshine.

I also remember reading about  an experimental reactor in the USA that was
purposelly allowed to go  critical while suspended in air, leading to the
death of nearby pine  trees.  Does anyone remember the name of that
