     Gustavo:
     
     A good reference addressing the use of Fly ash as a building material 
     is an OECD publication entitled, "Exposure to Radiation from the 
     Natural Radioactivity in Building Materials"' Published in May 1979.  
     In addition I have seen some references in UNSCEAR reports. As for 
     measuring flux there are a number of paper published in Health Physics 
     and Radiation Protection Dosimetry. If you need any more information 
     contact me by e-mail.

Hi Radsafers!
     
     
I'm evaluating from the radiological point of view the use of coal fly ash 
as an additive to cement, raw material for aggregates and bricks and 
substitute of sand in building materials. 
I know that some European and Asiatic countries implemented already the use 
of coal fly ash in building materials. 
I'll appreciatte information on regulation and uses of coal fly ash in 
building materials. I'd like to know measurement procedure for the 
measurement of radionuclide concentration and Rn-222 exhalation from the 
building materials containing fly ash.
     
Thanking everybody in advance,
