Nevada Test Site Radionuclide Inventory and Distribution Program: Report number 5: Areas 5, 11, 12, 15, 17, 18, 19, 25, 26, and 30

Corrective Action Decision Document for Corrective Action Unit 140: Waste Dumps, Burn Pits, and Storage Area, Nevada Test Site, Nevada: Revision No. 0

“…Locations A01 and A03 have Pu-239 concentrations above PALs; however, due to atmospheric testing in Area 5 these isotopes are not considered to be related to activities conducted at CAS 05-08-01 (McArthur and Mead, 1989). See Section A.2.7.1 for further information.…”

Composite Analysis for the Area 5 Radioactive Waste Management Site at the Nevada Test Site, Nye County, Nevada

“…In 1982, the Remote Sensing Laboratory (RSL) performed aerial radiation surveys of Areas 5 and 11 using NaI(T1) detectors mounted on helicopters. Elevated gamma exposure rates from residual radioactive contamination were detected only at Frenchman Flat playa, the Kay Block House, GMX, PIN STRIPE, and the Project 56 site (McArthur and Mead, 1989).…”

“…The inventories at these sites are poorly known, but are believed to be small based on the results of aerial surveys and the histories of the sites. The Kay Block House was reportedly used for hydrodynamic studies of depleted uranium targets (McArthur and Mead, 1989). The Kay Block House was detected by aerial gamma survey, but the contaminated area was relatively small.…”

Streamlined Approach for Environmental Restoration Plan for Corrective Action Unit 107: Low Impact Soil Sites, Nevada Test Site, Nevada

“…These areas are controlled to limit the spread of contamination. (McArthur and Kordas, 1983;1985;McArthur and Mead, 1987;1988;1989). A summary report was also published (McArthur, 1991) that provided an integrated estimate of the levels of soil radioactivity at the NTS, including estimated quantities of the 16 most significant man-made radionuclides produced by nuclear weapons testing.…”
