System and method enabling the behavior of radioactive substance within a structure to be determined

A method enabling the behavior of a radioactive substance within a structure to be determined, wherein the method comprises the process steps of:

• charging the radioactive substance with an acid of a certain molarity to a column via a column inlet;
• collecting the radioactive substance at the top of a column body, more specifically at a column inlet end;
• guiding the acid, which is used for charging, to the waste effluent via a column outlet;
• changing the molarity of the acid introduced to the column inlet and thus enabling the charged radioactive substances, which are intended to be separated, to move within the column;
• moving a radioactivity detector along the column body after the start of said movement;
• and
• realizing the scanning process.
