The half-life of 26Al is 7.17×105years. This is far too short for the isotope to survive to the present, but a small amount of the nuclide is produced by collisions of argon atoms with cosmic ray protons.\n The analysis of AL26 is part of the process to determine exposure ages."^^xsd:string; a dbpedia:Index_term .
