GSWA South Yilgarn merged and levelled 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）或称伽马能谱法（gamma-ray spectrometric method），可通过探测地球表面附近由钾（potassium）、铀（uranium）与钍（thorium）自然放射性衰变产生的伽马射线，测定该类伽马射线的天然波动特征。本数据集采集自联邦政府、各州政府、北领地（NT）政府及私营部门开展的航空地球物理调查。
