The reconciliation of the measured gamma dose rates with the field observations of soil thickness values, the potential vegetation types, and land use

Stage of soil degradation	Soil thickness (cm)	Gamma dose rate (nSv/h)	Soil type	Potential natural vegetation	Land use
0 (preserved)	> 30	> 89	Intact brown forest soil or loess	Deciduous forest	Arable land, suitable for forestry
1 (low)	20–30	82–89	Thick soil with some carbonate debris	Xerothermic deciduous forest	Rather, suitable for forestry
2 (medium)	5–19	65–82	Thin soil with carbonate debris	Xerothermic shrub vegetation	Suitable for grazing or planting black pine forest
3 (high)	5>	65>	Bedrock with a thin skeletal soil	Open or closed rocky grassland	It has no agricultural importance
