Housing versus Radon Issues Again

[steve.meith@internet.nps.usace.army.mil]

     Dear subscribers:
     
     My understanding on the issue(s) is that the studies did not take into 
     account exposure to silica, radioactive and non-radioactive 
     respirable/inhalable dusts or other possible airborne chemicals       
     generated by the mining activities.  
     
     I am hoping that at least one of you know if my impression is correct 
     or would be so kind as to provide me with the name and address or 
     someone who might be able to clarify this issue for me.  
     
     I am aware that quartz and cristobalite (common forms of crystalline 
     silica) have recently been classified as known human carcinogens, and 
     that crystalline silica is quite apt to be found in areas where 
     uranium ore is located.  I also do not know exactly which methods were 
     used for mining uranium at the time.  Is it possible that internal 
     combustion diesel fueled equipment was used in the mines? 
     
     Please note that I am NOT trying to inflame anyone, or myself for that 
     matter, I am merely seeking further understanding on the Rn vs housing 
     issue and would greatly appreciate any enlightenment which you or your 
     cohorts might provide.
                
                                Sincerely,
                                Stephen Meith
