Abstract : The total tritium activity absorbed on structural steel, galvanized steel, brass and aluminum was found to be less than 10 micro-c of tritium/sq cm of surface for exposure concentrations of 0.23 mc of tritium/cu cm in air and an exposure time of one hour. Tot total tritium activity adsorbed on a carbon steel surface is much greater than for the other surfaces. An increase in the total tritium activity adsorbed with increasing tritium exposure concentration was observed for all the metals studied. The nature of this increase, assuming a clean surface, appears to depend on the surface texture of the material. At a constant exposure concentration (0.11 mc of tritium/cu cm) no significant change in the total tritium activity adsorbed was observed for exposure times from 15 min to 4 hr. (Author)
