文摘
- •
Introduces a tool to calculate
from soil 134/137Cs activity concentrations.- •
Tool can model arbitrary depth profiles and horizontal distributions of radiocesium.
- •
Good correlation found between predicted and observed air dose rates.
- •
Main uncertainty in each prediction is due to sampling error for the soil activity.
- •
Topsoil removal and soil layer interchange are most effective remediation methods.
