Long counter (LC) is one of the standard instruments in neutron source flux measurements. Its counting efficiency is independent on the neutron energy and can be useful device in many neutron physics applications. In this paper, LC effective center for a 241 Am-Be neutron source has been measured in two cases one with source inside a collimator and other with bare neutron source. The effective center for the neutron source inside collimator and under bare conditions has been measured to be 13.5 cm and 9.5 cm, respectively. Using effective center and flux at various distances, the emission rate of the source has been estimated. Neutron emission rate was found to be (4.78 ± 0.164) Χ 10 7 and (4.92 ± 0.37) Χ 10 7 n/s for the source inside the collimator and bare source, respectively. This technique is one of the useful methods to determine neutron emission rate and for neutron fields' calibration.
