Other reactive casings for thermonuclear weapons have been proposed, and even tested, such as compound fission-fusion-fission weapons. However, the cobalt device seems best adapted to use as an enhanced radiation weapon as cobalt 60's 5 year half-life gives a good compromise between duration and radioactive intensity. | Other reactive casings for thermonuclear weapons have been proposed, and even tested, such as compound fission-fusion-fission weapons.
