GSWA Esperance 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 method），或称伽马射线光谱法（gamma-ray spectrometric method），用于测量地球表面附近探测到的伽马射线的自然变化——这些变化由钾、铀和钍的自然放射性衰变所致。这些数据通过英联邦、州及北领地政府与私营部门开展的航空地球物理调查收集。
