RE: DOE 5400.1 What is "Dry"?

["Morgan, Ben" <ben.morgan@cplc.com>]

David,

Section 7.3 of NUREG/CR-5489, "Manual for Conducting Radiological
Surveys in Support of License Termination," discusses sample
preparation. For soil samples it states, "If non-volatile elements are
the only contaminants of concern the samples are dried at approximately
110 C for a minimum of 12 hours; volatile radionuclides (H-3, Tc-99, and
iodides) must be separated from the sample before drying to avoid loss
of the radionuclide of interest."
