Report of the IAEA – PTB bilateral comparison: Reference air kerma rate for high dose rate 192Ir and 60Co brachytherapy sources

A comparison of the standards for reference air kerma rate of the Physikalisch-Technische Bundesanstalt (PTB) and of the International Atomic Energy Agency (IAEA) was carried out with 192Ir and 60Co high dose rate brachytherapy sources in May 2017. Comparison results were calculated based on the calibration coefficients for the transfer standard and expressed as the ratio of the IAEA and the PTB values. The comparison results were 1.0022 (uc = 0.0065) and 1.0022 (uc = 0.0065), k = 1, for 192Ir and 60Co sources, respectively.
