GSWA Byro 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.

放射性测量法（radiometric），亦称伽马射线能谱法（gamma-ray spectrometric），该方法通过检测地球表面附近由钾、铀、钍的天然放射性衰变所产生的伽马射线的自然变化，实现对相关辐射的量化测定。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勘测工作。
