The content ratios of hydrogen (H) and deuterium (D) in the hydrogen-containing films were determined by the Elastic Recoil Detection Analysis of the Transmission layout (T-ERDA) using 8 MeV He ion beams. For Mylar films, the determined D/H ratios and corresponding D densities (atoms/cm³) were (1.65 ± 0.08) × 10^-4 and (5.75 ± 0.28) × 10¹⁸, respectively. This study demonstrates that T-ERDA is widely applicable for nondestructive measurement of D/H ratio in materials.
