Best practices concerning qualification tests of radon passive detectors recommend the application of radon standard atmospheres at controlled conditions. A measurement technique has been developed, based on the application of the new on/off alpha track passive radon detector developed at ENEA. The capability of switch and pumping functions of this device has removed the time lag due to the radon transfer inside its sensitive volume and the post-exposure due to the residual radon decay. A special exposure facility has been developed based on a set of the above passive detectors connected with flange adapters to a radon chamber wall. This apparatus can be used substantially as a radon exposure standard (RES). Results of standardization tests at the ENEA Radon Facilities are given. The paper also addresses requirements for simple and small exposure facilities that permit accurate timed exposures and can be used for testing passive devices. © 2005 Elsevier Ltd.
