This study tries to understand the transfer process from the sources to the both polar regions (Greenland and Antarctica) of Iodine-129 and Chlorine-36. Time course profiles in both ice cores and newly obtained data for surface ice are discussed considering the places and timing of the atmospheric weapon testings and the operation conditions of spent nuclear fuel reprocessing plants.
