Maralinga
From Tardis Wiki, the free Doctor Who reference
Maralinga was an area in the Australian desert.
It was also home to the Maralinga Nuclear Weapons Test Site. In 1957, the United Kingdom detonated a hydrogen bomb there resulting in the area becoming radioactive.
The Seventh Doctor, Ace and the Counter-Measures group encountered the Markarians in Maralinga in 1967. (COMIC: Operation Volcano)
