Abstract The new neutronrich isotope 228 Rn was produced by spallation reactions induced by 600 MeV protons in a 232 Th target and identified by massseparation and decay spectroscopy. The Zassignment was confirmed via KX-rays and the genetic relationship to the wellknown daughter product 228 Fr. The halflife of 228 Rn is 65±2 s. Energies and relative intensities of prominent γ-rays are presented for the first time from the decay of both the new isotope 228 Rn and 227 Rn.
