     I am no radon expert, but I would suspect that soil moisture has 
     a big influence on radon emanation from soil.  
     Dr. Tom Borak at Colorado State University may (should) be able 
     to spread more light on this subject.

Dear Radsafe:
     
Radon concentrations(and daughter concentrtions) in OUTDOOR air 
fluctuate hourly, dialy etc. but most noticably from winter to 
summer.  What factor (s) are primarily responsible for the
more significant seasonal fluctuations? From limited search of 
literature - my first guess would be pressure differentials 
(produced by temperature differences between soil and air) 
pulling soil gas out of soil more in summer than winter?
     
Thanks
