CurrentBETTER INFORMATION ON PROPERTIES OF SOILRisk assessment of polluted and unpolluted sites asks for objective and quantitative methods for site investigation. Small sites are often mapped by coring, sampling and successive laboratory analyses used for the assessment of chemical pollutants, sediment characteristics or nutrients.For larger sites, sampling is virtually impossible because of time and costs involved whilst geophysical mapping systems give only a qualitative image of the site of study. This qualitative image is often not suitable for a quantitative risk assessment and decision making for local authorities.We have developed strategies for quantitative, spatially-detailed mapping using gamma spectrometer systems. Our case studies show the broad application of this approach, under water and on land.
