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.
“These surveys were well worth the effort,” said Juan Griego, acting manager for the Los Alamos Field Office. “The results are good news and the information will benefit the lab and the community for years to come as we work toward cleanup and sustainability.”
The 2011 survey focused on the White Rock community and Los Alamos National Laboratory, over which a specially equipped helicopter from Nevada’s Remote Sensing Lab flew approximately 150-feet above ground to gather radiological data.
The 2012 survey concentrated on the Los Alamos town site. That survey gathered data from 300 feet above the ground in order to limit noise to residents and animals, specifically the horses on North Mesa. Measurements taken from the flyover are equivalent to measurements taken from one meter above ground.
