Measurements from two recent aerial flyovers to determine the presence of background and man-made radioactivity brought good news for Los Alamos County and Los Alamos National Laboratory.
The radiological surveys, conducted in August 2011 and June 2012, found that radioisotopes and their associated exposure rates are consistent with those expected from normal background radiation.
The survey provided valuable data in several areas. First, the information updates a radiological survey conducted in 1994. Secondly, the survey showed the Las Conchas fire from 2011 did not impact background radiation levels. It also provides additional confirmation that the Rendija Canyon area remains at natural background radiation levels. There is an area north of Rendija Canyon under evaluation for return to public use.
The information will be incorporated into the lab’s Long-Term Environmental Stewardship and Sustainability Strategy report .
