Abstract

A radon chamber based on a single radium-226 source has been realized at ''Sapienza'' University of Rome. It allows radon measurement systems calibration at different radon air-concentration values. The design of the chamber required the solution of a set of differential equations deriving from a fluid dynamic Eulerian approach. The practical realization was carried out by developing a tailored microprocessor-managed hydraulic circuit. A set of experimental measurements has been carried out demonstrating both the tightness of the chamber and the capability of establishing and maintaining different radon concentrations.
