The authors report data on tritium permeation at 323 K and 373 K through annealed and single crystal copper for comparison with earlier data on unannealed copper, and show that tritium transport along grain boundaries or other lattice defects controls the overall rate at 323 K in unannealed material. Measurements on unannealed and annealed gold foil also indicate the importance of defect transport, although with gold the authors could not reduce the defect concentration sufficiently to measure permeation through the metal lattice. They also include permeation data on aluminum, molybdenum, tungsten, beryllium, cadmium, tritium, lead, rhenium, and silver; all of these were probably dominated by tritium transport along lattice defects.
