Transuranics in Sub-surface Soil. Based upon a study of the history
of test operations, upon soil profile data reported in NV-140, and
upon the results of the Fission Product Data Base Program (if appli-

required on this istand.

Transuranics in Sub-surface Soil. Based upon a study of the history
of test operations, upon soil profile data reported in NVO-140, and
upon the results of the Fission Product Data Base Program (if applicable), a diligent search was conducted, as outlined in Attachment #2,

For the purpose of this certification, the term Transuranies 1s defined

as those radionuclides measured and calculated by the ERSP to guide the
Enewetak cleanup, i.e., 239 Pu, 240 Pu and 241 Am.

Surface, in this context, refers to the layer of soil observed by the
in-situ detector in itS normal measuring position. It is generally
taken as approximately 3 cm in depth.
