The effect of the Bean-Livingston surface barrier on the thermoactivated relaxation of magnetization and critical current in superconducting ceramics is analyzed. The following picture of flux dynamics is discussed. At first, magnetic flux penetrates into intergranular regions, and then flux lines o
