Sentence examples for ground concentration from inspiring English sources

The radiometric (gamma-ray) data provide detailed (~70 m along-line) ground concentration estimates of the heat-producing radioelements.

The magnitude of the impacts is quantified by Cmax, the maximum observed concentration during release, while the time scale of the impact, τrecovery, the required time duration to recover to within (100 ± 5%) of its back ground concentration.

Conventionally secular equilibrium in the decay chains of uranium and thorium is assumed (Minty 1967) and the ground concentration results are reported as equivalent uranium (eU, ppm) and equivalent thorium (eTh, ppm).

It is possible to compare the airborne ground concentration estimates (obtained 'in-air' and representing a large surficial area) with radioelement concentrations obtained by point-located, field geochemical sampling and subsequent laboratory analysis.

Studies have found correlations between satellite aerosol optical depth (AOD), which describes the mass of aerosols in an atmospheric column, and PM2.5 ground concentration measurements in the eastern and mid-west USA [ 13- 17] and other land parts of the world [ 18- 20].

The author of this paper believes that the practical methods currently used for the evaluation of ground concentrations in these cases deserve some improvement.
