Abstract
A method for determining cleaning action on medical instruments and other objects is disclose. The method uses a predetermined soiling substance, for example fresh blood mixed with a radioactive marker. The soiling substance is applied to the instrument as a predetermined contamination. By making various radiation and time measurements one can determine in absolute mass units either the remaining soiling after the completion of a cleaning process or the soiling prior to the cleaning process. By comparing the determined masses one may validate specific cleaning processes, machines or agents.
