GSQ East Isa South 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（又称伽马射线能谱法）可检测地球表面附近的伽马射线自然变化，该变化源于钾、铀、钍的自然放射性衰变。本数据集由英联邦、各州及北领地政府与私营部门开展的航空地球物理调查采集获取。
