Bromine
…decay mode of isotopes lighter than 79Br is electron capture to isotopes of selenium; that of isotopes heavier than 81Br is beta decay to isotopes of krypton; and 80Br may decay by either mode to stable 80Se or 80Kr. Br isotopes from 87Br and heavier undergo beta decay with neutron emission and are of practical…
