PROBLEM TO BE SOLVED: To provide a soil contamination state estimation method capable of more efficiently determining a soil decontamination effect in a wide site, and significantly reducing a time and labor required for inspection of a decontamination state in the site.SOLUTION: A configuration of a soil contamination state estimation method estimates a soil contamination state in a wide site, and is configured to: measure or calculate a space dose rate which is detected at plural heights, about plural typical states of the soil; calculate a relative dose which is a ratio to the space dose rate at a reference height about each of the space dose rates at the plural heights; create a curve which is drawn by the relative dose with respect to the height, as a reference curve in each state; measure the space dose rates at the plural heights, at a predetermined measurement point; determine an actual measurement curve at the measurement point; then compare the actual measurement curve and the plural reference curves, for estimating the contamination state of the soil.SELECTED DRAWING: Figure 1 |
