RAdon contamination

["Les Slaback, Health Physics" <SLABACK@micf.nist.gov>]

TV screens: the papers I have seen clearly demonstrate that there is little     
correlation between the contamination levels  deposited on a CRT and the level  
of radon daughters in the air.  So monitoring the CRTs is not a valid way       
of estimated the radon level.                                                   
                                                                                
                                                                                
Object contamination: We have had the experience of seeing contamination on     
the order of 100's of dpm per swipe of machined plastic components.  The        
plastic is presumed to retain a good static charge which makes it a good        
collector.  [Just another oddball fact]
