A new radon gas dosemeter (patent pending) has been designed and tested to be used as a routine referenced device to monitor radon exposures in workplaces and dwelling. It has been conceived as a practical tool to be effectively used in the practice of a qualified Service, operating under Q.A. Monte Carlo simulation has been extensively used to optimize the geometry of the sensible volume of the holder; the diffusion of the sole radon gas is achieved by the special assembly of the holder, which behaves as closed type with air gap. In this paper we introduce, besides a general description of the device, the theoretical results carried out by Monte Carlo simulation, about the sensitivity tothe radon gas and the homogeneity of the detector track density.The experimental calibrations were executed at the two ENEA facilities (the National Metrology Institute and the radon Casaccia Laboratory) and at NRPB radon chamber.
