values for exemption of sealed Radioactive sources

[Kathleen McIntyre <mcintyre@mail.sep.bnl.gov>]

Does ANYONE know how the exemption values for sealed sources were derived
for DOE N 441.1, Attachment 1?  What is the technical basis for the values?!?

We're trying to construct a table to list isoptopes not specified in the
attachment...unfortunately, our numbers don't jive when comparing our
calculated values to those of 441.1


Thanks in advance,
