Nuclear Test program Operation Greenhouse Including Dog, Easy, George and Item Nuclear Test Blasts.

Operation Greenhouse nuclear weapons testing was conducted in the months of April and May of 1951. This test series consisted of four weapons related test shots from the 300-foot level on towers on the Enewetak Atoll Pacific Ocean. Two of these weapon tests greatly aided the pursuit of a hydrogen, or thermonuclear, weapon.

These tests were carried out by the Atomic Energy Commission. The test shots were:

Dog, April 7, 81 kilotons
Easy, April 20, 47 kilotons
George, May 8, 225 kilotons
Item, May 24, 45.5 kilotons

The George experiment was particularly important. It proved a hydrogen bomb (H-bomb) was possible and led to a crash development program for the first true thermonuclear weapon. Item was the first test of the boosting principle, which involved increasing the yield of a weapon.
