STATISTICAL ACTIVITIES DURING 1976 AND THE DESIGN AND INITIAL ANALYSIS OF NUCLEAR SITE STUDIES

摘要

Statistical design and analysis activities for the Nevada Applied Ecology Group (NAEG) during 1976 art briefly outlined. This is followed by a description of soil data collected thus far at nuclear study sites, Radionuclide concentrations in surface soil collected along a transect from ground zero (GZ) along the main fallout pattern are given for Nuclear Site (NS) 201. Concentrations in soil collected at 315 locations on a grid system at 200 foot spacings are also given for this site. The 241Am to 137Cs ratios change over NS 201 depending on location relative to GZ. They range from less than one where 241Am is at low levels, to more than fifty where 241Am levels 4re high (near GZ).
