Arunta Complex (Lake Mackay Mt Doreen) rad

The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of potassium, uranium and thorium. The data are collected on airborne geophysical surveys conducted by Commonwealth, State & NT Governments and the private sector.放射能法（radiometric，亦称伽马射线能谱法（gamma-ray spectrometric）），可通过检测地球表面附近的伽马射线自然变化，反映钾、铀、钍的自然放射性衰变所产生的辐射特征。本数据集的数据来源于澳大利亚联邦、州及北领地（NT，Northern Territory）政府与私营部门开展的航空地球物理调查。
