Measurements of characteristic gamma ray spectra resulting from A(n, n’γ)A reactions induced by 14
MeV neutrons on different bulk samples (graphite, water, melamin) were performed. Of particular ...importance are results of experiments with objects buried in the soil. It has been shown that samples of graphite can be identified when buried under 10
cm of soil.
NaI(Tl) and BaF
2 scintilators were used as gamma ray detectors. Background radiation was reduced by the associated alpha particle technique.
