AB  - A comparison of calibration results and procedures in terms of air kerma length product, P-KL, and air kerma, K, was conducted between eight dosimetry laboratories. A pencil-type ionization chamber (IC), generally used for computed tomography dose measurements, was calibrated according to three calibration methods, while its residual signal and other characteristics (sensitivity profile, active length) were assessed. The results showed that the partial irradiation method is the preferred method for the pencil-type IC calibration in terms of P-KL and it could be applied by the calibration laboratories successfully. Most of the participating laboratories achieved high level of agreement ( GT 99%) for both dosimetry quantities (P-KL and K). Estimated relative standard uncertainties of comparison results vary among laboratories from 0.34% to 2.32% depending on the quantity, beam quality and calibration method applied. Detailed analysis of the assigned uncertainties have been presented and discussed. (C) 2015 Associazione Italiana di Fisica Medica. Published by Elsevier Ltd. All rights reserved.
