Abstract

Two 9Ве(d,n)- neutron sources have been developed and produced at the NSC KIPT. Neutrons result from the interaction of accelerated deuterons with the nuclei of beryllium target in reaction 2Н+9Ве→10В+n. One of the sources is large-sized neutron source (LNS) with the medium energy of 5 MeV [1]. The neutron source is aimed to produce 99Мо by the reaction 98Мо(n,γ)99Мо. The maximum fluence in a limited volume is provided by the polyethylene or Be moderator. The 9Be moderator, except deceleration, provides reproduction of nucleons due to the (n,2n) reaction. The second source is a portable (PNS) with a medium energy of 2,5 MeV [2]. It is intended for the treatment of a number of oncological diseases. The major part of the dose in the phantom is absorbed in close vicinity of the neutron source ∼(1,5-2 сm). The fast neutron yield is about 109 neutron/s. The present paper deals with the possibility of using modern techniques of measuring of neutron radiation to build of relatively simple, compact, sensitive neutron detector on the proposed sources. It is shown that the neutron detector based on LiI(Eu) can be considered as one of the effective options for the measurements of neutron fields.
