Re[2]: Decontamination of Pu facilities

[Robert Owen <Robert_Owen@health.ohio.gov>]

     I was involved with decontamination of a FUSRAP site in upper state 
     New York.  We used vacuum blasting successfully to remove fixed 
     contamination down to acceptable levels.  The isotope was uranium. 
     As long as the end of the nozzle was held at the surface of the 
     concrete, there was no airborne contamination to deal with.  We 
     conducted air monitoring constantly in the enclosed space to ensure 
     this was the case.  The effort was effective and efficient.

     The information that you seek is available in the commerical market. 
     You might try ChemNuclear, U.S. Ecology or Allied Group Technology.  
     You might be lucky and get the information on the RADSAFE board 
     without any associated cost...You can acquire this information, 
     however, it requires that you PAY to PLAY...Good luck

I have been assigned the task of assisting with the decontamination 
and possible dismantling of a retired Pu facility.  I am seeking 
advice (no condolences please) and proven methods of decontaminating 
and/or fixing alpha contamination in place.  I have had the honor of 
working with Pu/Am in the past, but I always welcome any good 
advice.  
     
Areas that would be beneficial are: "Vacuum Blasting" technology and 
products that could be sprayed or introduced as a vapor to attach to 
the contamination and reduce the airborne contamination levels with 
out loading HEPA prefilters and that will not readily dry out.  
     
Send advice or equipment recommendations to:
