The National Tritium Labeling Facility (NTLF) was located on the eastern edge of the Lawrence Berkeley National Laboratory (LBNL) in Building 75. Just to the north of the NTLF is the Lawrence Hall of Science, a popular children's science museum that is visited by thousands of children every year.

The research effort reported on here has three primary objectives: 1) to monitor tritium activity levels in rainfall near the Lawrence Hall of Science, and creeks draining the watersheds close to the NTLF stack; 2) to date wood samples from Eucalyptus trees growing between the NTLF stack and the Lawrence Hall of Science; and, 3) to determine the organically bound tritium content of the dated samples as a means of reconstructing tritium emissions from the NTLF stack. These three objectives are covered in Part A, Part B, and Part C of this report.

This research was completed money allocated during Round 1 of the Citizens’ Monitoring and Technical Assessment Fund (MTA Fund). Clark University was named conservator of these works.
