    ABSTRACT: As required by different international agreements, the regulatory body in Spain (Consejo de Seguridad Nuclear) implemented in 1992 a national automatic network (REVIRA) that continuously monitors radiation levels in order to give early warning of incidents having potential transboundary implications. The detector for environmental gamma-radiation dose rate is an active instrument based on a Geiger-Müller counter. However, the use of passive environmental dosemeters provides an additional low-cost dose estimate with an independent centralised calibration and even better basic features than active instruments. Since 1999, all 25 REVIRA stations have been monitored with passive TL environmental dosemeters based on LiF:Mg,Cu,P and operated according to the procedures established at Ciemat. This paper presents the obtained results and the further analysis considering differences in aspects such as photon energy response, inherent background or response to cosmic rays. The benefits of the use of passive environmental dosemeters in early warning networks are discussed.

    ABSTRACT: In 1992, the Consejo de Seguridad Nuclear (CSN) implemented the Spanish Environmental Surveillance Radiological Automatic Network, REA, that continuously monitors radiation levels in order to give early warning of incidents having potential transboundary implications. The network includes 25 automatic radiological and meteorological stations distributed nation-wide, including the Balearic and Canary islands Radiological instruments at each ERA station provide dose rate measurements and also monitor airborne radionuclide concentrations (alpha, beta, radon and radioiodine). In 1998 CIEMAT and CSN found as a common interest the development of Quality programs and the optimisation of operational procedures for the REA network. The initial agreement has been recently extended to include continuous gamma airborne spectrometry. The co-operation includes the comparison of the radiation data reported by REA to those obtained independently with reference instruments operated by CIEMAT and other studies regarding quality assurance: gamma dose rate type testing, assessment of the calibration and evaluation procedures, data interpretation. The paper summarises the experience gained and the benefits obtained under this collaboration.
