Source strength determination in iridium-192 and cobalt-60 brachytherapy: A European survey on the level of agreement between clinical measurements and manufacturer certificates
2021, Physics and Imaging in Radiation OncologyCitation Excerpt :Other 192Ir standards are based on indirect methods for realization of RAKR [8]. The primary standard at NPL determines source strength values and instrument calibration coefficients with lower uncertainty (<1%) than the indirect ones (around 3%) at k = 2 [8–10]. The PTB provides a calibration for HDR 60Co sources and reported on a quality correction factor, kQ, aimed to transfer a 192Ir calibration coefficient into one for 60Co as derived from measurements with 35 well-type ionization chambers of two different chamber types [11,12].

2014, BrachytherapyCitation Excerpt :This method was found consistent and remains unchanged after a recent revisit (4). Extensions and minor changes have been developed and include data making it possible to exchange 137Cs for 60Co (5) and the use of more than one x-ray quality (6). The various approaches have been analyzed in detail and although some conceptual problems were found, these were insignificant in practice (7).
