PIRSA SAEI B3 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，亦称伽马能谱法，gamma-ray spectrometric method）可测量地球表面附近探测到的伽马射线的自然变化，这类伽马射线源于钾、铀、钍的自然放射性衰变。本数据集的数据由英联邦、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所得。
