METHOD AND DEVICE FOR DOWNHOLE NON-ISOTOPIC GENERATION OF NEUTRON RADIATION Russian patent published in 2012 - IPC G01N23/00 G01V5/04 

FIELD: physics.

SUBSTANCE: laser light (14) is excited in a multistage laser light amplifier (12) by means of a pump-type laser light source (13) so as to form a pulsed laser light (14a). Incoming laser light energy is concentrated in restricted laser light pulses representing a higher amount of light energy than that of the continuous flux of laser light (14); a drop (16a) of a neutron-enriched fluid is formed within a space (23) in a vacuum chamber (15); the pulsed secondary laser light rays (14b, 14c) are focused and directed toward the drop (16a) from substantially diametrically opposite directions, at a point in the drop (16a), the drop (16a) consequently being compressed and heated so as to cause the neutron-enriched fluid in the drop (16a) to emit neutron radiation (28) to the surroundings (5), thereby forming a high-energy reverberation, at least in the gamma frequency range, from the surroundings (5).

EFFECT: eliminating radiation hazard associated with use of radioactive isotopes.
