The Australian Royal Commission was unable to determine if Maralinga Tjarutja or Pila Nguru people had been exposed to damaging levels of radiation from fallout, due to the lack of medical records and medical centres. Maralinga bomb plume maps show prevailing northerly winds during tests, whereas the Spinifex lands are 300 km to the west of Maralinga. The closest group was at Nurrari Lakes about 180 km west. Scott Cane's otherwise definitive native title study, "Pila Nguru" (2000), contained almost no details as to how bomb testing radiation affected the Spinifex people.
