title: Realization and characterization of a ²²⁰Rn source for calibration purposes.
abstract: The recent interest for measuring (220)Rn activity in air and the following development of the corresponding measurement techniques require the improvement of standards for the calibration and characterization of the measurement devices. Due to the short half-life of the (220)Rn, the adopted techniques for the production of (222)Rn sources are not always reliable. In this paper a methodology for realizing a thoron known activity starting from a (232)Th source will be presented and discussed.
