 A paper on the radioisotopes left on an island by the French nuclear bombs tests of the 20th century has been printed by the International Atomic Energy Agency and a section of this report deals with plutonium contamination resulting from such tests.Other related trials were conducted at Maralinga, South Australia where both normal bomb detonations and "safety trials" have been conducted.While the activity from the fission products has decayed away almost totally (as of 2006) the plutonium remains active.
