Re:Final Radon Barrier Covers

[RADSRVS@aol.com]

Dear Colleagues/List members


I am in search of vendors/contacts that can provide the appropriate cover(s) 

for radioactive mill tailings (Ra-226,Th-232) piles to be secured on a site 

awaiting future disposal.  The pile will be about 40,000cu. yards.  The 

concentrations range is 5pCi/g to 2500pCi/g for Ra-226 and Th-232.  We need 

to limit the Radon release rate below 20pCi/L/m2s.


Any help would be appreciated.


This is a Superfund Site.


Kindest regards,
