Shot ITEM of Operation Greenhouse, 1951. ITEM was the first test of a "boosted" nuclear weapon, where the efficiency of the reaction is increased by fusion reactions in the core of the bomb (but it is not a true "hydrogen bomb"). The turquoise color just present in the center of the fireball is in the original photograph.
