Transplutonium neutron activation logging technique |
| abstract |
A typical embodiment of the invention enables neutrons of low average energy that characteristically are emitted from californium 252 (Cf252) to react with, or fail to react with, nuclei within an earth formation, depending on the energy threshold for the reaction in question. The neutron activation induced by means of the Cf252 source is compared with the response induced in the formation through neutrons of higher average energies from other sources, The activation comparison permits the identification of elements and minerals in the formation to be determined accurately. |
