PIRSA TEISA North Callabonna 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.

辐射测量法（radiometric method），亦称伽马射线能谱法（gamma-ray spectrometric method），通过检测地球表面附近的伽马射线，对由钾、铀、钍自然放射性衰变所产生的伽马射线天然变化量进行测量。该数据集采集自英联邦、各州及北领地（NT）政府与私营部门开展的航空地球物理勘探工作。
