The calibration (in rad/nC) of an air-filled tissue-equivalent ionization chamber for neutrons of l5-MeV average energy was determined by measuring absolute fluences and calculating the kerma per unit fluence. The neutron calibration determined from the ..gamma..-ray calibration and application of the Bragg--Gray relation was found to be 4% higher than that based on the fluence measurement. Additional data were taken to obtain calibration factors with tissue-equivalent gas; the same difference betwen the two methods was observed.
