(1) Release of plutonium, americium and curium could occur from laboratory or industrial accidents.
(2) All isotopes of curium are radioactive with curium - 247 having the longest half life, about 16 million years.
(3) Kept secret until after the war, they were respectively called americium and curium .
(4) It is prepared artificially by bombarding curium with alpha particles in a particle accelerator.
(5) The lifetimes of the first u251cu00f6u251cu00e7u251cu2510transuraniumu251cu00f6u251cu00e7u251cu00fb elements - such as plutonium, curium and californium - were very close to the values predicted by the liquid-drop model.
