Barlee Jackson 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 method）或伽马射线能谱法（gamma-ray spectrometric method）可量化地球表面附近探测到的伽马射线的自然波动，此类波动源于钾、铀与钍的自然放射性衰变。本数据集的相关数据采集自英联邦、各州政府及北领地政府与私营部门开展的航空地球物理调查。
