By using a newly developed procedure for experimental determination of the neutron sensitivity function of a dosimeter, results were obtained for a commercially available graphite ionization chamber. The n/$gamma$ sensitivity as a function of neutron energy from 1 to 20 MeV is presented for the air-filled chamber as well as for continuously flowing CO$sub 2$, O$sub 2$, and argon. Similar results obtained for homogeneous tissue-equivalent chambers are presented for comparison. A detailed discussion of uncertainties in the final results is presented. (auth)
