Abstract

Moisture density gauges (MDG) are widely used in monitoring soil and pavement properties but emit gamma and neutron radiation that could pose a health hazard. Neutron dose absorbed received by the personnel from using an MDG was determined using neutron thermoluminescence dosimeter (TLD). Result shows Neutron dose levels received were comparable with gamma dose that could exceed the safe dose limits for radiation workers. It was also shown that radiation backscattering differs with dry and moist media.
