FIELD: investigating or analyzing materials.
SUBSTANCE: method includes measuring intensity of radiation at a number of sites. The object is irradiated from two opposite sides alternatively by pulse flux of high-speed neutrons with individual recording of radiation passed through the volume. The device has blocks for decoding of gamma- and neutron radiation. The detector of neutrons is composed of low-speed neutron counters, controller for processing information, power source, control desk, and computer.
EFFECT: expanded functional capabilities.
