TRANSLUCENT ZnS/10B CONVERTER NEUTRON SCINTILLATOR AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a neutron scintillator enabling a neutron imaging measurement at a high count rate in a high gamma ray background, and a method for manufacturing the same.SOLUTION: The method for manufacturing a translucent ZnS/B converter neutron scintillator comprises: mixing aB concentrated boric acid (HBO) having aB isotope concentration of 90% or more with a hardener using modified alicyclic polyamine, modified aliphatic polyamine or aliphatic diamine as a main material to prepare aB-amine mixture; mixing theB-amine mixture with water, ethyl alcohol, methyl alcohol, a mixture of water and ethyl alcohol or a mixture of water and methyl alcohol to prepare aB containing transparent adhesive material; mixing a ZnS based phosphor with theB containing transparent adhesive substance to prepare a ZnS based phosphor-B containing transparent adhesive material; and applying the ZnS based phosphor-B containing transparent adhesive material on a substrate to dry and solidify the coating.
