GSWA Broome North Canning 1 ppm Uranium Grid Geodetic

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.

放射测量法（radiometric method），亦称伽马射线能谱法（gamma-ray spectrometric method），可测量由钾、铀及钍的自然放射性衰变所引发的、在地球表面附近探测到的伽马射线的自然变化。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勘探项目。
