 Are there any guidance documents or precedents on the wall thickness of
instruments used for contact dose rate readings on US DOT shipments
pursuant to 49 CRF 173?  For example if an instrument designed for deep
dose measurements records a contact dose rate below release limits  and
a reading with the shallow dose window open is over the limit which
reading applies?
