GSWA Gascoyne 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.

放射测量法（radiometric），又称伽马射线能谱法（gamma-ray spectrometric），可探测地球表层附近因钾、铀、钍发生天然放射性衰变而产生的伽马射线自然变化。该数据集采集自英联邦、各州及北领地政府与私营部门开展的航空地球物理测量工作。
