The previous 45 years of experimental data on the properties of point defects in Pt were considered in terms of a modified 2-interstitial model. After low-temperature irradiation, correlated <100>-split interstitial-vacancy pairs annihilated in recovery-stages I and II; with activation energies which ranged from very small values up to the activation energy (0.73eV) for the migration of free <100>-split interstitials. Free <100>-split interstitials recovered in stage-III, at about 300K, and vacancies recovered in stage-IV, at about 600K. The recovery of vacancies after quenching was also observed in recovery-stage IV, and their activation energy for migration was 1.37eV. Di-vacancies which were obtained by quenching had an activation energy for migration of 1.1eV and annihilated in a temperature range below that which corresponded to the range of recovery-stage IV.
