Resuspension Factors

[Danny_L_Rice@rl.gov]

     I am looking for background data concerning resuspension factors for 
     equating surface concentration (Bq/m^2) to potential airborne 
     concentration (Bq/m^3).  I have seen resuspension factors ranging from 
     10-4 to 10-8 (heavy activity to light activity) and would like to 
     better understand the experimental basis.
     
     Any assistance in locating references is appreciated.
