Integration technique for neutron source standardization inside A cylindrical water tank

Abstract

This work deals with the evaluation of neutron irradiation facility. Two (Pu-Be) sources and two (Ra-Be) sources are used. Integration technique by a BF3 detector for neutron source standardization is used. The necessary calibrations have been performed, and all the possible known errors have been taken into consideration. The total error using this technique does not exceed ± 10%. This assembly is capable of safely accommodating the neutron sources and of permitting work inside the assembly without any hazard. Moreover, the availability of such neutron irradiation facilities with isotropic neutron sources provide a promising tool for applications to neutron activation analysis.
