Detecting Radioactive Anomalies

The low penetrating power of alpha and beta particles make them unlikely to be detected during field surveys. Instead, most radiometric surveys concentrate on detecting gamma rays. The low attenuation rate of gamma rays passing through air make both ground … Continue reading

Detecting Density Anomalies

Gravity field surveying is a passive technique to detect gravity anomalies. Gravity is a global field that always points vertically down, with anomalies caused by very small variations in density of the underlying materials. A gravity base station measures the … Continue reading
