Seeking background data on cinder block

[Tony Mason <trm2tony@netscape.net>]

Radsafers:  I'm looking for referenceable data on the naturally 

occurring activity concentrations in cinder block.  The activity range 

provided in NCRP 94 is very broad and I don't have any previous analysis 

results for this material.  I would not be releasing any material or 

performing final status with the data.  If someone could lead me to or 

provide a resource for this information I'd very much appreciate it.  

Thanks in advance.  Tony
