Prompt gamma-ray analysis was applied to determine hydrogen in geological samples. In order to obtain accurate values, blank values were estimated and subtracted. Samples were dried to constant weight in an oven. Helium gas was introduced into the sample box to purge the air containing moisture during the measurement. Hydrogen contents in some geochemical standard samples were determined and highly reproducible values were obtained.
