WebS.K. Haldar, in Mineral Exploration, 2013 5.7.1 Concept The radiometric surveys detect and map natural radioactive emanations (γ ray) from rocks and soils. The gamma radiation takes place from the natural decay of elements like U, Th and K. The radiometric method is capable of detecting these elements at the surface of the ground. WebGravimeters used in geophysical surveys have an accuracy of about 0.01 milligal (mgal; 1 mgal = 0.001 centimetre per second per second). That is to say, they are capable of detecting differences in the Earth’s gravitational field as small as one part in 100,000,000. Gravity differences occur because of local density differences.
