LAS VEGAS (AP) — The National Nuclear Security Administration says air and groundwater around the Nevada National Security Site tested as safe last year.
A report released Monday says no airborne radioactivity was detected off the test site in 2010. It also shows the public is not exposed to man-made radionuclides in groundwater.
Officials say that the radioactive isotope tritium that was detected outside the test site boundary at the Nevada Test and Training Range continues to stay at levels below the legal limit for safe drinking water. That finding was originally reported in 2009.
Air and groundwater monitoring is conducted by a contractor that manages the test site, and the citizen-run Community Environmental Monitoring Program that gets direction from the Desert Research Institute.
A network of 29 air sampling stations monitors radioactivity.
