Abstract Segregation of chemical impurities in ice formed from very dilute solutions was observed autoradiographically, using radioactive 22 NaCl or H 36 Cl as β -ray tracers. When water containing such radioactive solutes was frozen, the segregation of solute occurred primarily along grain boundaries and partly in grains. Successive autoradiography enabled us to observe the heterogeneous distributions of segregated impurities in ice.
