The suitability of cryogenic vacuum extraction for sampling free water (F-water) extracted from environmental materials (grass and soil) was examined with respect to low-level (~ 1 Bq L−1) and precise determination of tritium (3H) concentrations in

The carbon to hydrogen ratio (C/H ratio, w/w) in plants is a key factor in estimating the amount of hydrogen in the photosynthetic product. The amount of hydrogen calculated from photosynthetic model estimation associated with the C/H ratio is an ess
