Gamma Spectrometers
A gamma spectrometer is an active instrument which emits and gamma-rays and receives the reflection of the absorbed of emitted pulses. The energy difference between the emitted and received pulse are used to identify particular elements and isotopes. Because these elements and isotopes absorb the energy pulse or emit energy, an identifiable fingerprint for each element is created. Gamma spectrometers are used in mining to map soil properties and geology or, as for example, radioactive pollution, in agriculture to measure soil density and soil moisture content.
