Table 1 Details about the irradiation conditions for the establishment of calibration curves of each participant. The column “Curve” indicates whether a participant used a curve established in its own laboratory or a curve from another source. The columns “No. doses” and “Maximum dose” indicate the number of dose points and maximum dose used for calibration curves. For columns “Number doses”, “Maximum dose” and “Blood samples irradiated in”, parameters for manual and semi-automatic (in parentheses) scoring are provided and the hyphen “-” in the column indicates that the corresponding scoring mode was not performed or the information was not available. The column “Dosimetry” indicates whether the doses for the irradiations for the establishment of the calibration curve were given as air kerma or absorbed dose to water.
