The half-life of ^54Mn is 312.2 days and main γ-energy is 835keV, therefore it is used as a standard source for a multi-channel analyzer and a dose calibrator and managanese catabolism study in human body. In this paper, a method for the production of no carrier added ^54Mn was studied via ^54Cr(p,n) and ^59Co(p, αpn), with MC-50 cyclotron and described chemical isolation method of ^54Mn from a irradiated target by ion exchange resin. Chromium and cobalt were used as target materials. The production yields of ^54Mn by 50.5 MeV protons was 4.5 μCi.μ/Ah on chromium target and 11.85 μCi/μAh on cobalt target. The cross-section and thick target yield of ^59Co(p, αpn)^54Mn reaction were measured in the energy range of 50.5→22.2MeV in order to determine the optimum conditions for the production of ^54Mn. the maximum cross-section was 47.48 mbarn at 41.2MeV.
