ADDENDUM TO TECH NOTE 2.19: TOTAL TRANSURANICS ON ISLET EDNA DOE/ERSP TECH NOTE NO. 2,19-A DATED: June 1978 AUTHOR: M. Barnes, DRI Data from surface soil samples have become available for eight additional locations, with four composites for all but three locations, which had two composites each. Minimum, maximum and Mean total transuranics from the composites are listed below for the additional locations. The islet is too small to do the in situ 241Am gammasurvey, so a ratio of total transuranics to americium was not computed. These data do not affect the conclusions contained in the transmittal letter dated 20 May 1978.

Friesen, DRI Soil Samples were taken from the surface only at six locations with two composites at each location. Minimum, maximum and mean total transuranics from the two composites are listed. A ratio of total transuranies to americium was not computed for Sally's Child since the islet is too small to do the in situ 241Am gamma survey.
