Monitoring and Release of Porous Materials and Items With Inaccessible Surfaces

["Redmond, Randy R. (RXQ) " <RXQ@y12.doe.gov>]

Trying to locate guidance documents, procedures, regs, notices, site
positions pertaining to monitoring and release of porous materials, such as
wood, and items with inaccessible surfaces, such as railroad ties with deep
cracks.  The DOE RADCON Manual uses language such as "disassemble to the
extent required to perform an adequate survey" and similar language can be
found in other documents.  Have you established a percentage of the limit,
e.g., 25%, that you use to separate questionable items from others?  Of
course, one can never rule out the most important aspects of a survey -
history of the item, common sense, and professional judgement.

Thank you,
