Radioactive Neighbor: Lawrence Livermore National Laboratory (702 KB)

In December 2003, The RadioActivist Campaign (TRAC) began a 5 month radiological survey around LLNL’s perimeter to monitor the lab’s releases of artificial radioactivity into the surrounding environment. TRAC sought to identify and sample air and waterborne pathways that could potentially release radioactivity. TRAC’s study served a “Red Team” role to determine whether LLNL completely reports all of its artificial radioactive releases.

TRAC then analyzed those samples in its in-house broad-band spectrometric laboratory. TRAC’s analysis is relatively sensitive to most nuclear fission and activation products, but not to tritium or plutonium.

TRAC used the results of the December study to plan follow-up monitoring in May 2004. The follow-up monitoring provided confirmations of positive “hits” and checks on alternative explanations for those results. This is TRAC’s final report from the December 2003 and May 2004 radiological monitoring around LLNL.
