Abstract
Results are presented for a study of hydrogen concentration profiles o btained by the elastic recoil detection technique for samples of a sta inless steel contaminated by hydrogen during service, comparing the da ta with those obtained for samples of the same material after cathodic hydrogen-charging in the laboratory. Through-thickness hydrogen conce ntration profiles were calculated from the proton energy spectra obtai ned, identifying potentially dangerous maximum hydrogen concentrations from 2 to 14 ppm (by weight).
