Antimony depth profile

Figure 31 RBS spectra and depth profile for aluminum with implanted antimony.

At site A in Table 16, concentrations of all metals in the second soil-core depth were higher than those in the first soil-core depth. Bismuth and antimony concentrations in the soil core under the second core depth were less than those of natural concentrations, 0.34 and 0.37 /rgg , respectively. At sites B and C, the profiles of metal concentrations were somewhat different from those in site A The difference is probably due to dissimilarities in pollution history, surrounding circumstances and properties of soil.
