As part of the Radionuclide Inventory and Distribution Program on the Nevada Test Site, in situ measurements of gamma-emitting radionuclides were made at more than 600 locations in six regions near ground zeros in Areas 18 and 20. In addition, several soil samples were collected from each region and analyzed to determine inverse relaxation lengths and radionuclide ratios. Analysis of the data from Area 20 led to estimated inventories of 23 Ci of /sup 241/Am, 30 Ci of /sup 238/Pu, 41 Ci of /sup 239,240/Pu, 18 Ci of /sup 60/Co, 6.4 Ci of /sup 137/Cs, 6.0 Ci of /sup 90/Sr, 17 Ci of /sup 152/Eu, 19 Ci of /sup 154/Eu, and 6.6 Ci of /sup 155/Eu. For Area 18, the estimated inventories were 27 Ci of /sup 241/Am, 4.9 Ci of /sup 238/Pu, 150 Ci of /sup 239,240/Pu, 1.3 Ci of /sup 60/Co, 4.9 Ci of /sup 137/Cs, 13 Ci of /sup 90/Sr, 2.1 Ci of /sup 152/Eu, 1.3 Ci of /sup 154/Eu, and 1.4 Ci of /sup 155/Eu. The locations of the measurements in Area 18 were chosen by importance sampling, which permits the calculation of an estimate of the sampling error. Maps of radionuclide distributions were also generated for all regions except the area near the Palanquin and Cabriolet ground zeros. 3 refs., 65 figs., 7 tabs.
