Abstract

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.

Abstract

At the ENEA Institute for Radiation Protection (IRP) the fast neutron calibration facility consists of a remote control device which allows locating different sources (Am–Be, Pu–Li, bare and D2O moderated 252 Cf) at the reference position, at the desired height from the floor, inside a 10 � 10 � 3m 3 irradiation room. Either the ISO reference sources or the Pu–Li source have been characterised in terms of uncollided H � ð10Þ and neutron fluence according to the ISO calibration procedures. A spectral fluence mapping, carried out with the Monte Carlo Code MCNP TM , allowed characterising the calibration point, in scattered field conditions, according to the most recent international recommendations. Moreover, the irradiation of personal dosemeters on the ISO water filled slab phantom was simulated to determine the field homogeneity of the calibration area and the variability of the neutron field (including the backscattered component) along the phantom surface. At the ENEA Institute for Radiation Protection the calibration of neutron area monitors as well as personal dosemeters can now be performed according to the international standards, at the same time guaranteeing suitable conditions for research and qualification purposes in the field of neutron dosimetry. r 2002 Elsevier Science B.V.
