Abstract

The advantages and limitations of epithermal neutrons in qualification of hydrocarbons via their H contents and C/H atomic ratios have been investigated systematically. Sensitivity of this method and the dimensions of the interrogated regions were determined for various types of hydrogenous samples. Results clearly demonstrate the advantages of direct neutron detection, e.g. by BF3 counters as compared to the foil activation method in addition to using the hardness of the spectral shape of Pu-Be neutrons to that from a 252Cf source.
