| Radionuclides in surface soil at the Nevada Test Site | |
| McArthur, R D | |
| 英文摘要 | In 1981, the US Department of Energy began the Radionuclide Inventory and Distribution Program, an attempt to assess the amount and distribution of radioactivity in surface soil at the Nevada Test Site (NTS). Over the next several years, researchers used a combination of aerial radiological surveys, soil sampling, and in situ measurements to study the regions of the NTS where soil radioactivity was above background levels. These regions included the ground zeros of above-ground nuclear tests, underground tests that vented, and some safety shots, as well as the sites of nuclear rocket experiments. The results of the program were published in a series of five reports between 1983 and 1989. In this report, those results have been combined to provide an integrated picture of the current levels of soil radioactivity on the NTS. The estimated inventories of the nine most important manmade radionuclides have been reviewed (and in some cases recalculated), decay-corrected to January 1, 1990, and tabulated. New distribution maps have been prepared that show isopleths of decay-corrected radionuclide concentrations over the entire NTS. Two additional maps show the measurement locations where the gamma exposure rate exceeds 100 {mu}R/hr and where the {sup 239, 240}Pu concentration exceeds 500 pCi/g. 21 refs., 12 figs., 6 tabs. |
