A new determination of the 109Cd half-life was made by a time series of measurements of an aqueous sample using a re-entrant type ionisation chamber. The measurement campaign covered a period of 6 years or approximately 4.7 half-lives of 109Cd. The resulting value of 462.1 (3) days is in good agreement with the recently published values of 462.29 (30) days and 462.3 (8) days (Van Ammel et al., 2011; Unterweger and Fitzgerald, 2014). This work will contribute to a revised evaluation of the currently available data and, possibly, to improving the standard uncertainty in the evaluated 109Cd half-life value.
