The results of determination of impurities contained in an artificial neutrino source in the BEST experiment are presented. A @
Cr source of activity 3.6 MCi was produced by exposing enriched chromium to thermal neutrons in a nuclear reactor. The amount of impurities was estimated by lines in the spectrum of photons from the source. It is shown that the contribution of radioactive isotopes associated with the impurities to the energy deposition in the source is negligible in relation to the energy deposition of
Cr. A high purity of the material from which the source was manufactured is demonstrated. The cross section for neutron capture by a number of elements is estimated.
