Antimony--beryllium sources offer a cheap way of obtaining intense neutron fluxes up to l0/sup 10/ neutrons/sec and can be made in the following way: Antimony is irradiated in a reactor to form Sb/sup 124/ and inserted into a beryllium cylinder, which emits neutrons by the gamma ,n reaction. Since Sb/sup 124/ has a half life of 60 days, the source should be reactivated 2 or 3 times a year. The advantages of the source are that it is inexpensive, rnns continuously, and gives off a nearly monoenergetic neutron beam at 25 kev similar to reactor thermal colurm fluxes. When separated from the beryllium, the antimony provides an intense gamma radiation of 10/sup 4/ r/hr at 1 ft with a mean energy of 1.05 Mev. Other aspects of the source are treated, e.g., shielding and costs. (D.L.C.)
