Method for estimating the depth of contamination of concrete bodies, method for determining the depth of chipping, and method for removing contamination

摘要

PROBLEM TO BE SOLVED: To provide a method for estimating a pollution depth of a concrete body, which can accurately estimate the pollution depth in a short time. SOLUTION: This is a method for estimating the pollution depth of a concrete body contaminated by contact with contaminated water containing a harmful metal element or a radionuclide, wherein the depth of the concrete body from the contact surface with the contaminated water is x, and concrete. The time from the start of contact between the body and the contaminated water is t, the predetermined standard value for the target harmful metal element or radionuclide is C0, the depth x, and the concentration of the radionuclide at time t is C ( A method for estimating the depth of contamination of a concrete body, which includes a step of finding the minimum value xmin of x satisfying the equation (1), where x, t).
