Sulfur analysis in bulk samples using a DD portable neutron generator based PGNAA setup

Prompt gamma ray analysis of sulfur-contaminated soil samples was carried out using a Genie 16 DD portable neutron generator and a 12.7 cm × 12.7 cm (diameter × height) BGO detector. The minimum detectable concentration MDC ±  $$\sigma_{\text{MDC}}$$ was measured from soil samples containing 4.4, 7.1, 9.6, and 13.47 wt% sulfur using the 5.42 MeV sulfur capture gamma rays. The measured value of MDC ±  $$\sigma_{\text{MDC}}$$ for sulfur, which was 1.30 ± 0.40 wt%, is in good agreement with the corresponding values reported earlier with intense 252Cf source-based PGNAA setups.
