AIR-GAP TECHNIQUE IN MEASUREMENT OF DENSITY BY NUCLEAR SURFACE DENSITY GAGE

Errors due to soil composition variation effect, the inherent uncertainties in counting rate measurement and the effect of rough and irregular soil surfaces affect the density measurements by nuclear gages. The air-gap method using the dual-gage principle has been successfully used for minimizing these errors in the field measurements. A comparison of different calibration relations is also made in the case of air-gap method. (Author/TRRL)
