The half-life times of the relatively short-lived -decaying isotopes and were measured with a hybrid pixel detector of Timepix3 technology. Radon daughter products were collected at the backside of a 1 mm thick silicon sensor so that subsequent decays inject the polonium isotopes of interest shallowly into the backside of the sensor. The detector’s high spatial and time resolution allow for particle identification and application of the delayed coincidence technique with low systematic uncertainty even at high rates. We find and . Studying the decay of the accumulated radon daughter products after removing the detector from the field, the half-life time of the -decay of was measured to be . The results are discussed in the context of previous works.
