SUMMARY REPORT
Since the October, 1974, meeting of the Nevada Applied Ecology Group
(NAEG), a number of projects have been implemented and completed by
LFE Environmental.
The principal function of the laboratory during
the reporting period was to provide NAEG contractors with analytical
data for samples collected in the field or prepared in the laboratory.
Approximately 2,300 data results for soil,
were sent to NAEG-NV.

and mammals
Approximately 500 pieces of data for soft
tissue, bone, and rumen contents in large grazing mammals were also
transmitted to NAEG-NV.

Results from 1,000 data for filters, salta-
and vegetation were also transmitted to NAEG-LLL.
Computer programs were devised for reporting these data to each
group.
All the above projects required analysis for a variety of nuclides,

Procedures for ashing,
and analysis of nuclides in filters,
dis-
soils, vegetation,
saltations, and small mammals were greatly improved through many
hours of research and development work.
Americium-243 tracer recovery,
for example, was increased from an average 30 to 60%, in addition to
a considerable improvement in the quality of the electroplate.
