Curves of counting rate versus moisture content are presented, for sand, loam and clay soils, using (i) a 1000 me Ra-Be source surrounded by a small rigid indium cylinder acting as detector of slow neutrons and (ii) two co-axial Cd cylinders protecting the indium detector. Improved accuracy in the region of low moisture contents was obtained with (ii). (Abstract retrieved from CAB Abstracts by CABI’s permission)
