Obelisk at the Totem One test site. Emu Field (also Emu Junction or simply Emu) is the site of Operation Totem, a pair of nuclear tests conducted by the British Government in South Australia during October 1953. [1] The site was surveyed by Len Beadell in 1952. A village and airstrip were constructed for the subsequent testing program. [2]
Two separate atomic test projects occurred at the islands, the first being Operation Hurricane and the second being Operation Mosaic.Following the second Mosaic explosion, the radioactive cloud that was supposed to be taken away from the site, was sent back by wind that was not anticipated by the British scientists.
The detonation produced a crater 1.9 km (6,200 ft) in diameter and 50 m (160 ft) deep where Elugelab had once been; [9] the blast and water waves from the explosion (some waves up to 6.1 m (20 ft) high) stripped the test islands clean of vegetation, as observed by a helicopter survey within 60 minutes after the test, by which time the mushroom ...
Operation Totem was a pair of British atmospheric nuclear tests which took place at Emu Field in South Australia in October 1953. They followed the Operation Hurricane test of the first British atomic bomb, which had taken place at the Montebello Islands a year previously.
Used for the Vela Uniform test Long Shot, it was tested for the larger role when Faultless in central Nevada proved that area unsuitable. The Millrow test showed suitability, and the island was used for the 5 Mt Cannikin test, the largest underground test ever performed. Plowshare Sites: Carlsbad, New Mexico

Five tests were conducted at the K site at Emu Field, about 13 kilometres (8 mi) from the Operation Totem test site on 26 and 30 September and 6, 14 and 17 October 1953. [124] These experiments dispersed about 36 grams (1.3 oz) of beryllium and 407 curies (15,100 GBq) of polonium-210 into the surrounding area. [125]
Operation Sandstone was a series of nuclear weapon tests in 1948. It was the third series of American tests, following Trinity in 1945 and Crossroads in 1946, and preceding Ranger.
