MEASUREMENT OF GAMMA RAY ENERGY DUE TO INELASTIC NEUTRON SCATTERING
Patent
·
OSTI ID:4038577
A well-logging device is described which is based on the fact that certain elements (C, 0, and S), but not other elements (Na, Fe, Mg, and Cl), in earth formations emit characteristic gamma rays when bombarded by neutrons of a selected energy. The device is an exploring unit designed to travel along a bore hols and which contains a neutron source and a gamma detection system (scintillator, photomultiplier, and pulse height analyzer). The neutron source, which gives off neutrons of energy at least 2.3 Mev, is either a tritiumdeutenium reactor or a Ra-Be source; in the latter case, a lead shield is interposed between the source and the detector to block off the gamma rays emitted by the source.
