Dual Energy Gamma-ray Transmission for Coincident Measurement of Water Content and Dry Bulk Density of Soil

GAMMA-RAY transmission has several advantages for the measurement of the water content or dry bulk density of soils, provided that only one of these properties varies 1,2 . It is important when working with layered soils that a high degree of sample resolution is attained and this can be achieved by...

Description
Summary:GAMMA-RAY transmission has several advantages for the measurement of the water content or dry bulk density of soils, provided that only one of these properties varies 1,2 . It is important when working with layered soils that a high degree of sample resolution is attained and this can be achieved by counting unattenuated primary energy photons. In many field studies, however, considerable variations of both water content and dry bulk density occur together, and in such cases these properties have to be measured independently. A possible method of achieving this is considered in this communication.
