Abstract

A comparison was made between the NIST and ENEA air kerma standards for medium energy x-rays and 60Co gamma rays. The comparison took place at ENEA in June 1994. Two different transfer chambers from NIST were used for the comparison. The measurements were made at radiation qualities similar to those used at the BIPM (generating voltages of 100, 135, 180 and 250 kV respectively) and with 60Co gamma radiation. The agreement in this comparison was within 0.03% for 60Co gamma radiation and in the range between 0.1% to 0.8% for the medium energy x-ray qualities.
