PIRSA Ooldea Radiometric Line Data

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.

辐射测量法（radiometric）或称伽马射线能谱法（gamma-ray spectrometric method），可对地球表面附近探测到的、由钾、铀及钍的天然放射性衰变产生的伽马射线的自然变化进行测量。本数据集采集自联邦、各州及北领地政府与私营部门开展的航空地球物理调查。
