RE: Seeking background data on cinder block

["Boing, Lawrence E." <lboing@ANL.GOV>]

All-



I would recommend Eric Abelquist or someone down at ORISE in Oak Ridge -

they do tons of release surveys for NRC and DOE following D&D/ER to show

that sites are ready for release - I would think they must know what

this would typically be across the country at all the diff sites they

have worked at.

Tony,

This is going to depend heavily on the manufacturer of the blocks, the

location from which the production material came from and the process of

manufacture. I'm not sure if there is a generic value which can be

applied universally. Anybody out there have a better handle on this?

Mine is tenuous at best.

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
