The processes of neutron fluxes interaction with an aqueous solution ofmethyl orange organic dye have been investigated. The work was carried out on aLINAC LUE-300 at NSC KIPT. A set of tungsten plates was used as aneutron-generating target. The electron energy was 15 MeV, the average currentwas 20 mkA. The samples were located behind the lead shield and without it,with and without a moderator. Using the Geant4 toolkit for this experiment,neutron fluxes and their energy spectra were calculated at the location ofexperimental samples without a moderator and with a moderator of differentthickness (1-5 cm). An analysis of the experimental results showed that whenobjects without lead shielding and without a moderator are irradiated, the dyemolecules are completely destroyed. In the presence of lead protection, 10%destruction of the dye molecules was observed. When a five-centimeterpolyethylene moderator was installed behind the lead shield, the destruction ofdye molecules without boric acid on thermal neutrons was practically notobserved. When the fluxes of thermal and epithermal neutrons interacted with adye solution containing 4% boric acid, 30% destruction of dye molecules wasobserved due to the exothermic reaction 10B (n, a). The research has shown thatsolutions of organic dyes are a good material for creating detectors forrecording fluxes of thermal and epithermal neutrons. Such detectors can be usedfor radioecological monitoring of the environment, in nuclear power engineeringand nuclear medicine, and in the field of neutron capture therapy research inparticular.
