Gamma Ray sondes

     
    • Description
    • Specifications
    • The gamma ray sonde can be used on its own or in combination with other sondes.
    • The gamma ray sonde measures the natural radioactivity of rocks.
    • The result is expressed by variation curves of gamma radiation versus depth.
