Abstract: The method for assessing of radiocarbon on surfaces of solids materials used in low-background experiments is proposed. At the heart of this method is detection of the amount of carbon-containing substances on the surface of the materials using oxythermography. The method evaluates the amount of radiocarbon on the surface based on its percentage content in the total carbon. The method has been tested in laboratory rooms of two different institutions – JINR and Dubna University.

Keywords: oxythermography, assessing radiocarbon on surfaces of solid materials, low-background experiments.
