GSWA South Pilbara 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.

放射性测量法（radiometric），亦称伽马能谱法（gamma-ray spectrometric），可通过测量地球表面附近探测到的伽马射线，表征由钾、铀及钍的自然放射性衰变所引发的伽马射线自然变化。本数据集的数据采集自联邦、各州及北领地（NT）政府与私营部门开展的航空地球物理调查。
